Abstract

PROBLEM TO BE SOLVED: To selectively form only the music data of prescribed partial sections in forming the music data, such as melody. SOLUTION: Whether music data is to be formed by each of partial sections in one musical piece or not is set by the user's operation. The forming sections where the music data is formed and the non-forming section where the music data is not formed are discriminated according to this setting. The music data based on given music conditions is formed only relating to the forming sections and the formation of the music data is not carried out relating to the non- forming sections. The remaking of the music data by each of the partial sections in the already formed musical piece may be easily carried out. Even in creating new music, the music creation having degrees of freedom may be carried out. Since the music data may be simultaneously formed between the plural partial sections parted across the non-forming sections, this method is convenient.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic music apparatus and a method for automatically generating music data such as a melody or accompaniment in accordance with various conditions relating to music, a storage medium and a program, and more particularly to a music data generation method. It is possible to selectively generate or regenerate only the music data of a predetermined partial section.

[0002]

2. Description of the Related Art In recent years, with the spread of personal computers, anyone can freely play music using computer music that plays, composes, arranges, and synthesizes timbres using a computer. Now I can enjoy it. In particular, in the field of composition using a computer, automatic songs have emerged that can be easily enjoyed by even beginners with little musical expertise. As a conventional automatic music composition device, for example, various musical parameters (hereinafter, simply referred to as melody generation parameters) that characterize a melody such as key, beat, pitch jumping dynamics, presence / absence of syncopation, chord progression, and the like are input. There is known a melody that automatically generates a melody based on the melody generation parameters. When such an automatic music composition device is used, the user can easily and freely compose various melodies by selectively inputting the melody generation parameters.

[0003]

By the way, in the conventional automatic music composition device, a melody for the whole music is automatically generated based on the melody generation parameters. Therefore, if the user does not like only some of the generated melodies and does not like the melody again, the melody of the entire song is regenerated, and even the melody that did not need to be changed is regenerated. , There was a problem.
That is, the user cannot leave a part of the generated melody for use as it is, and regenerate only the melody of the other part. As described above, the conventional automatic music composition device is very inconvenient for the user.

[0004] The present invention has been made in view of the above points, and is easy to use by making it possible to generate or regenerate only music data of a specific partial section designated when generating music data such as a melody. It is another object of the present invention to provide an automatic music composition apparatus and method and a storage medium capable of generating music data with a high degree of freedom.

[0005]

SUMMARY OF THE INVENTION An automatic music apparatus according to the present invention automatically sets, on the basis of given music conditions, setting means for setting whether or not to generate music data for each partial section of music. The music data is generated in accordance with the setting, a generation section for generating the music data in accordance with the setting and a non-generation section for not generating the music data are distinguished, and the music data based on the given music condition is generated only for the generation section. Generating means for generating.

For example, the setting means can set whether or not music data should be generated for each partial section of a created music. As a result, the music data for the generated section for the created music is regenerated by the generating means, and the music data for the non-generated section for the generated music is saved without being regenerated. The created music is modified. As described above, since the music data, for example, the melody data is generated only for the designated section, the user can regenerate only a partial section of the melody that has been automatically composed. In other words, the music data can be regenerated as many times as desired only for the section where the melody is not liked. This makes it possible for the user to regenerate or generate music data that is easy for the user to use and that has a high degree of freedom, and that music data with a high degree of musical perfection can be generated by simple processing. In addition, since the generation of music data is prohibited for the non-generation section, the music data for two or more generation sections separated by the non-generation section can be generated at the same time. It is also a target.

Further, the automatic music device according to the present invention has a setting means for setting whether or not to generate music data for each partial section of the music, and automatically generates music data based on given music conditions. Generating a music data based on the given music condition only for the generation section by distinguishing between a generation section that generates music data and a non-generation section that does not generate music data according to the setting. Generation means, second generation means for generating music data in accordance with a passage symbol attached to each passage constituting the music, and priority is given to one of the first generation means and the second generation means And a music piece data is generated by the generation means specified by the priority specification means. Thus, the first generation means for generating music data based on a given music condition only in an arbitrarily set partial generation section, and the second generation for generating music data according to a phrase symbol By making it possible to designate either of the means to be given priority, it is possible to easily perform a musically reliable automatic music piece which gives priority to a passage symbol when the second generation means is given priority. In addition, when the first generation means is prioritized, the degree of freedom of composition by the user is increased, so that the user can easily reproduce and generate music data having a high degree of freedom, It will also be relatively easy to compose musically complete melodies.

Further, the automatic music device according to the present invention comprises a setting means for setting whether or not to generate music data for each partial section of the music, and automatically generates music data based on given music conditions. Generating a music data based on the supplied music condition parameter only for the generation period by distinguishing between a generation period for generating music data and a non-generation period for not generating the music data in accordance with the setting. 1 generating means, second generating means for generating music data in accordance with a passage symbol attached to each passage constituting the music, and generating the music data by the second generating means in the first generating means. Control means for prioritizing the generation of music data by In this case, by giving priority to the second generation means, for example, music data of the same passage symbol as the section in which the music data is already completed can be easily generated by copying. Automatic music can be easily performed. On the other hand, in a section in which the preceding section of the same section symbol does not exist, by generating the music data by the first generating means, it is possible to regenerate or generate music data having a degree of freedom. In this way, it is possible to regenerate or generate music data that is easy for the user to use and has a high degree of freedom, and it is also relatively easy to compose a melody with high musical perfection.

The present invention can be constructed and implemented not only as a device invention, but also as a method invention. Further, the present invention can be implemented in the form of a program of a computer or a processor such as a DSP, and can also be implemented in the form of a recording medium storing such a program.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a block diagram of a hardware configuration showing an embodiment of the entire configuration of the automatic music composition apparatus according to the present invention. The automatic music composition device shown in this embodiment is:
Microprocessor unit (CPU) 1, read only memory (ROM) 2, random access memory (RA)
M) 3 to be controlled by a microcomputer. The CPU 1 controls the operation of the entire automatic music composition device. A read only memory (ROM) 2 and a random access memory (RA) are supplied to the CPU 1 via a data and address bus 1D.
M) 3, detection circuit 4, switch detection circuit 5, display circuit 6, sound source circuit 7, effect circuit 8, external storage device 9, MID
An I interface (I / F) 10 and a communication interface 11 are connected to each other. Further, the CPU 1 is connected to a timer 1A that measures an interrupt time and various times in a timer interrupt process (interrupt process). That is, the timer 1A counts the time interval,
After completion of the composition, a tempo clock pulse is generated for setting a performance tempo when automatically performing the composed music. The frequency of the tempo clock pulse is adjusted by a tempo setting switch or the like among various switches 5A. Such a tempo clock pulse from the timer 1A is given to the CPU 1 as a processing timing command or given to the CPU 1 as an interrupt command. The CPU 1 executes various processes according to these instructions. The various processes include, for example, a screen display process for an automatic song and an automatic performance process for playing the automatically composed song. Note that the automatic music composition device is not limited to a dedicated device, and may be, for example, a general-purpose device such as a personal computer or a multimedia device, and performs automatic music composition by using predetermined software or hardware according to the present invention. What is necessary is just the apparatus comprised so that it can perform.

The ROM 2 stores various programs executed or referred to by the CPU 1, various data, and the like. The RAM 3 includes various musical sound information (for example, information on a hierarchical structure of a melody to be generated and information such as a melody generation parameter) used for generating a melody, automatic performance information used for automatically performing a composed music, and a CPU 1. Are used as a working memory for temporarily storing various data generated when a predetermined program is executed, or as a memory for storing a program currently being executed and data related thereto. RA
A predetermined address area of M3 is assigned to each function and used as a register, a flag, a table, a memory, and the like. The performance operator 4A is provided with a plurality of keys for selecting the pitch of a musical tone, such as a keyboard, and has a key switch corresponding to each key. Can be used not only for musical performance, but also as an input means for inputting the pitch and rhythm of the melody when composing. The detection circuit 4 detects pressing and releasing of each key of the performance operator 4A,
Generates a detection output. The panel controls (switches, etc.) 5A include various controls for designating various parameters or inputting various performance conditions during automatic performance. For example, a melody generation switch for selecting whether or not to generate a melody in a predetermined section, and a priority designation switch for designating whether to prioritize a passage symbol or a melody generation switch are included. Of course, in addition to the above, various operators such as a numeric keypad for inputting numerical data and a keyboard for inputting character data used for selecting, setting, and controlling pitch, tone, effect, and the like may be included. The switch detection circuit 5 detects an operation state of each operation element of the switch 5A, and outputs switch information corresponding to the operation state to the CPU 1 via the data and address bus 1D. The display circuit 6 displays various information such as a melody generation parameter and a melody generation setting state (described later) by a melody generation switch, for example, on a display 6A including a liquid crystal display panel (LCD), a CRT, or the like.
Of the automatic performance or the control state of the CPU 1 is displayed on the display 6A.

Here, the melody generation switch will be briefly described with reference to FIG. FIG. 2 is a conceptual diagram illustrating an embodiment of the melody generation switch. However, here, the switch displayed on the display 6A is turned on / off by clicking with a mouse or the like.
A melody generation switch in the form of a soft switch that can be operated has been described as an example. As can be understood from FIG. 2, the melody generation switch MS is displayed on the display 6A for each section of the melody to be generated. In this embodiment, the melody generation switch MS is provided for each phrase section that is the minimum section unit for melody generation. Melody can be classified into a plurality of sections, and melody generation is generated for each section. For example, when the melody is composed of two block sections (block 1 and block 2), the melody is generated for each block section. In addition, since the section unit of melody generation such as the block section can be constituted by a section of a smaller unit (that is, the melody has a hierarchical structure), the melody is generated for each smaller section unit. You can also. For example, one melody is composed of two block sections (block 1 and block 2), one block section is composed of two phrases (phrase 1 and phrase 2), and one phrase is composed of two phrases (phrase 1 and phrase 2). In such a case (that is, when one song is composed of 4 phrases and 8 phrases), a melody can be generated not only in blocks but also in phrases or phrases. Therefore, a melody generation switch MS is provided for each section in which the melody is generated. Of course, as shown in this embodiment, the melody generation switch M
The melody generation switch MS may be provided not only for providing S but also for each section section, each block section, or each shorter bar section (not shown). That is, the melody generation switch MS may be provided for each of a plurality of layers such as a phrase unit switch and a phrase unit switch.

In such a case, priority may be given to the setting of the melody generation switch MS of the upper unit (that is, the longer section), or to the lower unit (that is, the shorter section).
The setting of the melody generation switch MS may be prioritized. The priority designation is designated by a priority designation switch (not shown). When the setting of the upper unit melody generation switch MS is designated by priority, a melody is generated in accordance with the setting of the upper unit melody generation switch MS regardless of the setting of the lower unit melody generation switch MS. You. For example, even if the melody generation switch MS in the phrase section is set OFF (or ON), the melody generation switch MS in the section section is set.
Is ON setting (or OFF setting), the melody is regenerated according to the ON setting (or OFF setting) of the melody generation switch MS in the passage section. On the contrary, when the setting of the lower unit melody generation switch MS is preferentially designated, no matter what setting is set in the upper unit melody generation switch MS, the setting of the lower unit melody generation switch MS is performed. A melody is generated. For example, even if the melody generation switch MS in the phrase section is OFF (or ON), if the melody generation switch MS in the phrase section is ON (or OFF), the melody generation switch MS in the phrase section is set. The melody is regenerated according to the ON setting (or OFF setting). Note that any combination of the melody generation switches MS may be used as a higher order unit. For example, as shown in FIG. 2, phrase 1 and phrase 2 of phrase 1 of block 1 and phrase 2 of phrase 1 of block 2
May be provided.

When the melody generation switch MS is set to ON, a melody is generated for the ON-set section. In this embodiment, the melody generation switch MS
Are in the ON state, the respective sections of the phrases 1 and 2 belonging to the phrase 1 of the block 1 and the section 2 of the phrase 2 belonging to the phrase 1 of the block 2 are generation sections, that is, sections for which a melody is newly generated. . After generating the melody of the whole song, the generated melody is used as it is for the phrases 1 and 2 belonging to the phrase 2 of the block 1 and the phrase 1 belonging to the phrase 1 of the block 2, and the other sections (block 1 If you want to regenerate the melody for phrases 1 and 2 belonging to phrase 1 and phrase 2 belonging to phrase 1 in block 2), or if you want to generate only a new melody for some sections, etc. The melody generation switch MS in the section may be set to ON as shown in FIG.

As a method of setting the melody generation switch MS, when the switch is in the ON state, the section is set as a “melody generation” generation section, and when the switch is in the OFF state, the section is set as “melody generation”. A method of setting a “non-generating” section as a non-generating section (that is, the melody generating switch MS specifies a “generating melody” section), or a non-generating section of “non-generating melody” when the switch is ON. One of the methods of setting a section and setting the section as a “generate melody” generation section when in the OFF state (ie, the melody generation switch MS specifies a section that does not generate a melody) A case is conceivable, but either may be used. The melody generation switch MS is turned on (or turned off) when it is turned on, and is displayed on the screen of the display 6A (shown by a solid square in FIG. 2), and turned off (or turned on) when turned off. Then, the screen is displayed on the display 6A (in FIG. 2, it is represented by a rectangle without being filled).
This is very convenient because the user can understand the setting status at a glance. In other words, if the display is changed between the section where the melody is generated and the section where the melody is not generated, the user can determine at a glance whether or not the section is the one where the melody is to be generated. , A section to be subjected to melody generation can be set.

Returning to FIG. 1, the tone generator circuit 7 can simultaneously generate musical tone signals on a plurality of channels, and inputs data and performance information given via an address bus 1D.
A tone signal is generated based on the performance information. The tone signal generated from the tone generator 7 is generated via the sound system 8A. Further, the effect circuit 8 includes the sound source circuit 7.
Various effects are given to the tone signal generated from the sound signal. The tone signal generation method in the tone generator circuit 7 may be of any type. For example, a waveform memory reading method for sequentially reading out tone waveform sample value data stored in a waveform memory according to address data that changes in accordance with the pitch of a musical tone to be generated, or a method in which the address data is used as a predetermined A known system such as an FM system for performing tone modulation sample value data by executing a frequency modulation operation, or an AM system for executing tone amplitude sample operation by performing a predetermined amplitude modulation operation using the address data as phase angle parameter data. May be appropriately adopted.
That is, the tone generator circuit 7 uses a waveform memory method, FM
Any system such as a system, a physical model system, a harmonic synthesis system, a formant synthesis system, an analog synthesizer system of VCO + VCF + VCA, and an analog simulation system may be used. Further, the sound source circuit 7 is not limited to the configuration using the dedicated hardware, but may be configured using a DSP and a microprogram or a CPU and software. In addition, 1
A plurality of tone generation channels may be formed by using one circuit in a time division manner, or one tone generation channel may be formed by one circuit.

In the automatic music composition apparatus according to the present invention, the melody generation switch MS (see FIG. 2) provided in each predetermined section
The section is selectively determined according to the N / OFF setting state, and a melody (specifically, performance data relating to the melody) is automatically generated only for the selected section. An example of a process of automatically generating a melody only for a section selected according to the embodiment of the present invention will be described with reference to FIG. FIG. 3 shows ON / OFF of the melody generation switch MS.
9 is a flowchart illustrating an example of a process of selectively generating only a melody in a predetermined section according to a setting. When changing a created song, a desired song to be changed is selected in advance, and the process of FIG. 3 is applied to the selected song. Of course, the process of FIG. 3 is applicable not only to a case where an existing song is changed but also a case where a new song is created. Hereinafter, the processing operation in the processing will be described with reference to the flowchart of FIG.

In step S1, melody generation data (that is, parameters for setting music conditions for melody generation) are supplied. For example, the melody generation data input by the user operating the panel operator (switch or the like) 5A or the performance operator 4A (keyboard or the like), the melody generation data acquired from the external storage device 9, or the MIDI interface 10 or communication It supplies melody generation data and the like acquired from another MIDI device 10A or the server computer 11A via the interface 11. The melody generation data is various musical parameters that characterize the melody such as, for example, key, beat, pitch jumping dynamics, presence / absence of syncopation, and chord progression.
In step S2, a generation section (or a non-generation section) is designated by the melody generation switch MS. That is,
A generation section for generating a melody (or a non-generation section for not generating a melody) is determined according to the ON / OFF setting state of the melody generation switch MS. Then, as a preparation for generating a melody, the section at the head of the music is set as a section to be determined (step S3). At the time of melody generation, it is determined whether or not the section is a generation section (or whether or not it is a non-generation section) for each predetermined section sequentially from the head section of the music, and Only for the section determined to be a section (or only for the section determined not to be a non-generation section), a melody is generated based on the melody generation parameter ("re-generation" in the case of changing an existing music). Therefore, in the process of step S3, the head section of the music is set first as a determination target section so that determination can be performed sequentially from the head of the music at the time of melody generation.

In step S4, it is determined whether or not the automatic music processing for each section corresponding to the ON / OFF setting by the melody generation switch MS has priority over the automatic music processing corresponding to the phrase symbol. That is, whether to generate a melody for each section determined to be a generation section in accordance with ON / OFF setting by the melody generation switch MS and to perform processing with priority.
Alternatively, it is determined whether processing is performed with priority given to generating a melody in accordance with automatic music composition processing corresponding to a passage symbol.
In general, a song has a phrase configuration in which one or a plurality of phrases are combined, a predetermined phrase symbol is added to each phrase, and the songs are arranged in the order of the phrase for one song. It shows what the configuration is. A phrase symbol is a symbol indicating similarity / dissimilarity between phrases. For example, when one piece of music has a four-segment structure, "A" (or "A") is used as a passage symbol of the first passage,
“B” (or “A ′”) as the phrase symbol of the second phrase, “C” (or “B”) as the phrase symbol of the third phrase, and “C ′” (or “B”) as the phrase symbol of the fourth phrase "")), The passage composition is "ABCC '" (or "AA'
BB '"). In this example,
A melody similar to the phrase "A" is represented by adding a "'" (dash) symbol to the original symbol, such as "A'", and the melody is not similar to the phrase "A" (dissimilar) Is represented by another symbol “B”, “C”, or the like.
When the same phrase symbol is assigned to a plurality of phrases in a song, the same phrase generally has the same melody. Therefore, regardless of the setting of the melody generation switch MS, each phrase melody is copied as it is. Is good (that is, phrase symbol priority). However, the melody may be generated by giving priority to the setting of the melody generation switch MS rather than following the setting by the phrase symbol. Therefore,
In the present embodiment, the user selects which of (1) music data generation processing corresponding to a phrase symbol and (2) music data generation processing for each section according to the setting of the melody generation switch MS. , And a process according to one of the above (1) and (2) is performed in accordance with the designation by the priority designation switch. This priority designation may be performed not only by the switch but also by priority designation data. For example, it is possible to set and input a phrase symbol indicating a phrase configuration as one of the music conditions for melody generation, and to prioritize the process (1) for generating the music data corresponding to the phrase symbol, the setting is input. In the case where the music data generation process is performed in accordance with the set melody symbol, while the music data generation process for each section is prioritized in accordance with the setting of the melody generation switch MS described in the above (2), the switch MS is used for the setting. A music data generation process is performed for each of the selected sections. The process of generating music data according to a phrase symbol is, for example, when music data of a certain phrase (for example, the first phrase) of the phrase symbol A has been created, the same or similar phrase symbol (A or A) is used. As the song data of another passage (eg, the third passage) having '), the song data of the created passage (eg, the first passage) of the same or similar passage symbol A is copied, and based on the copied song data, This is the process of automatically composing (using the same or changing a part).

In step S4, it is determined which of the above-mentioned processes (1) and (2) is designated by the priority designation switch or the priority designation data. If the process of generating the music data for each section according to the ON / OFF setting by the melody generation switch MS in (2) is prioritized, "switch priority" is determined as YES, and each section is routed through steps S5 to S8. A music data generation process is performed for each song. On the other hand, when the ON / OFF setting by the melody generation switch MS does not take precedence over the setting by the passage symbol (N in step S4)
O) In the routes of steps S10 and S11, the process of giving priority to the setting of the phrase symbol, that is, the process of generating the music data corresponding to the phrase symbol of (1) is performed. That is, regardless of the ON / OFF setting by the melody generation switch MS,
Generate a melody based on a phrase symbol. When performing the music data generation process according to the above-mentioned section symbol (1), it is determined whether there is a section to which a section symbol identical / similar to the section symbol attached to the section is attached before the section (before the song). It is determined whether or not data has been created (step S10). Same /
If there is a section to which a similar phrase symbol is attached (YES in step S10), the created melody data in the section with the same / similar phrase symbol is copied as the melody of the section, and the melody data is created based on this. Generated (that is, diverted or partially modified) (step S1
1). This step S11 may be omitted if the generation of the section of the first phrase symbol of the same / similar phrase symbols has not been instructed yet. For example, "ABA"
If the first “A” phrase has not been instructed to be generated yet, the subsequent “A” phrase already has the same content as the first “A” phrase, so it makes sense to copy it at this stage. There is no need to execute step S11. After generating the melody of the section (ie,
After copying the melody), the process proceeds to step S9.

On the other hand, the melody generation switch MS
When N / OFF setting has priority (YE in step S4)
S) Or, if a section with the same / similar phrase symbol as the section symbol attached to the section does not precede (NO in step S10), whether the section is designated as a melody generation section It is determined whether or not it is (step S5).
That is, it is determined whether or not the melody generation switch MS of the section is set to ON. If the section is not designated as the melody generation section (NO in step S5),
The process jumps to step S9. When this section is designated as the melody generation section (YE in step S5)
S), a melody in the generation section is generated (see Steps S6 to S8 described later). That is, the melody music data is automatically generated sequentially for each section according to the ON / OFF setting of the melody generation switch MS. Step S
By the jump from S5 to S9, for example, the music piece data regenerating process (steps S6 to S8) is not performed for the section set as the non-generation section in the created music piece. The song data of the favorite phrase can be reliably stored.

When generating a melody, first, only the melody rhythm (sound generation timing information) in the generation section is generated (step S6). As a method of generating a rhythm, for example, a method of retrieving a rhythm pattern matching a genre of a song (for example, rock, jazz, classical music, or the like) from a predetermined database and adopting the same is known. Next, a pitch is assigned to each hit point (sound generation timing) of the generated rhythm (step S7). For example, an important hit point in the generated rhythm (a specific hit point in a predetermined section that characterizes the melody musically, such as the beginning of each bar or a strong beat) corresponds to the chord progression of the melody generation parameter. Randomly select and assign any one of the chord constituent sounds according to the above, and randomly select and assign any one of the scale tones constituting the key of the music to the hit points other than the important hit points. And
Melody matching processing is performed so that the melody matches between the generation section in which the melody is generated and an adjacent section (step S8). That is, when the pitch of the current generation section that is generating the current music data does not match the pitch of the section adjacent to the current generation section, the section adjacent to the current generation section is a generation section or a non-generation section. , The process of regenerating the pitch of the current generation section in which the current music data has been generated is performed. For example, the pitch of the last sound may be generated so that the pitch of the last sound of the current generation section matches the pitch of the first sound of the next section. If the pitch does not match the pitch of the sound (for example, the final sound is the pitch at which dominant motion is desired), a musically unnatural melody is generated between the generation section and the next section. Will be. Therefore, if the pitch of the first sound of the next section can be matched with the pitch of the last sound of the generation section (that is, if the next section is a generation section), the pitch of the generated final sound is adopted as it is. Then, when generating the next section, the pitch may be generated so that the pitch of the first sound matches the pitch of the last sound.

On the other hand, if the pitch of the first sound of the next section cannot be consistent with the pitch of the last sound of the generation section (ie, if the next section is a non-generation section), Reject the pitch and regenerate it to another pitch. That is, in this case, since the pitch of the first sound cannot be newly generated because the next section is a non-generation section, it is dealt with by regenerating the pitch of the final sound of the generation section. If the pitch of the last sound of the previous section of the current generation section in which the current music data is being generated does not match the pitch of the first sound of the current generation section, the first sound pitch of the current generation section is generated. fix. Further, as another viewpoint, there is a method of inputting a pitch jump degree of a melody as a melody generation parameter and generating a melody based on the pitch jump degree. It is preferable to perform the matching process between. For example, it is preferable that consistency is set so that the pitch jump degree is within the value input by the melody generation parameter. As is apparent, in the "music piece data generation processing for each section according to the setting by the melody generation switch MS" performed in the route of steps S5 to S8, the copy processing corresponding to the phrase symbol (step S11). Is not performed, so that step S1
Even if the music condition set and input in step S1 contains a phrase symbol, in the automatic music composition processing in the route of steps S5 to S8, the music composition process corresponding to the phrase symbol will not be performed.

In step S9, it is determined whether or not the section is the last section of the music. If it is the last section (YES in step S9), the melody generation process ends since there is no more section for which a melody is to be generated. If it is not the last section (NO in step S9), there is a possibility that there is a generation section in which the melody is to be generated in the following section, so the process proceeds to the section following the section (step S12). Returning to the processing of S4, the processing of steps S4 to S12 is repeated. In this way, a melody is newly generated or regenerated for each section (in the case of a generation section), or a melody that has already been generated is used as it is (in the case of a non-generation section), thereby partially changing the melody. 1
You can compose or change the melody of the whole song. The consistency processing (see step S8) may be omitted depending on the music genre for generating the melody, or when the level of the generated melody may be musically low. In addition, the melody generation method (step S6 to step S6)
8) is merely an example, and it goes without saying that an appropriate method may be used as the melody generation method.

Here, the melody generation in the case where the generation processing of the music data corresponding to the passage symbol is set to be prioritized will be described with reference to FIG. FIG. 4 is a conceptual diagram for explaining an operation of generating a melody according to a setting by a phrase symbol. ON with melody generation switch MS /
If priority is given to the process of generating music data for each section that has been set to OFF, melody music data is generated for a section that is specified to be a “generate melody” generation section by setting the melody generation switch MS to ON. . On the other hand, when priority is given to the music data generation process corresponding to the phrase symbols (NO in step S4 of FIG. 3), the same phrase symbol is assigned to a plurality of phrases (FIG. 4). In the example, the phrase 1 of the block 1 and the phrase 1 of the block 2 are both given the same phrase symbol "A".) Since the phrases of the same phrase symbol generally have the same melody, ON / OFF of the melody generation switch MS
Regardless of the OFF setting, the phrase melody of the same phrase symbol is copied and generated as it is. For example, as shown in the figure, when the phrase symbol of both the phrase 1 of the block 1 and the phrase 1 of the block 2 are “A”, the phrase 1 of the block 2 is related to the ON / OFF setting of the melody generation switch MS in the section. First, the melody of phrase 1 of block 1 is copied to generate the melody of phrase 1 of block 2.

The same applies to the case where similar phrases are given to phrases (for example, "A" and "A '"). . However, in this case, if it is specified that the setting of the phrase symbol takes precedence, the melody of the entire phrase is not copied and the melody is generated, but the music data of a partial section of the phrase is converted into the melody shown in FIG. The music data of another section may be automatically generated by the processing of steps S5 to S8 without copying in step S11 of FIG. For example, the melody of the entire section may be generated or regenerated by copying only the melody piece data of the first half of the section and generating or regenerating the melody piece data of the second section of the section. In this case, for example, in step S10 of FIG. 3, if the section currently being processed is the latter half of the passage, the process may branch to NO and go to step S5 or S6.
Of course, the present invention is not limited to this, and as described above, step S in FIG.
It is also possible to copy once in step 11 and change part of the copied music data as appropriate.

On the other hand, as described above, when the ON / OFF setting of the melody generating switch MS is prioritized (when step S4 in FIG. 3 is YES), the ON / OFF of the melody generating switch MS is not considered without considering the passage symbols. The music data generation processing is performed with priority given to the OFF setting. For example, in FIG.
The melody of phrase 1 of passage 1 of block 2 is fixed,
If it is desired to regenerate only the melody of phrase 2 of phrase 1 of block 2, even if phrase 1 of block 1 and phrase 1 of block 2 have the same phrase symbol A, ON / OFF setting of melody generation switch MS , And the section corresponding to the phrase 1 of the phrase 1 of the block 2 is turned off by the melody generation switch MS,
Turn on the section corresponding to phrase 2 of passage 1 of block 2
And

In the example shown in FIG. 3, it is possible to select and designate which of the setting by the phrase symbol and the ON / OFF setting of the melody generation switch MS by the priority designation switch or data. Instead, one of them may always be given priority. For example, it is possible to configure an embodiment in which music data generation processing according to a setting by a phrase symbol is always given priority. In such an embodiment, for example, when a phrase symbol is not included in the music condition, the melody generation switch MS is turned ON / OFF.
Performs generation processing according to the OFF setting, or follows the ON / OFF setting of the melody generation switch MS when the same or similar phrase does not precede even if the phrase symbol is included in the music condition. Perform generation processing,
It may be configured as follows. For this purpose, for example, step S4 in FIG. 3 may be omitted, and step S10 may always be performed from steps S3 and S12.

Conversely, the ON / OFF of the melody generation switch MS
An embodiment in which the music data generation processing according to the OFF setting is always given priority may be configured. In such an embodiment, under a predetermined condition, for example, when a melody regenerating process is instructed even when the melody generating switch MS is set to OFF in all sections, a tune corresponding to the phrase symbol setting is used. Data generation processing may be performed. Alternatively, the melody generation switch MS is turned on.
Only the music data generation processing according to the / OFF setting may be performed. For this purpose, for example, step S in FIG.
4, steps S10 and S11 are omitted, and steps S3 and S12
From step S5.

Further, as another embodiment or modification,
Even in the case of performing music data generation processing in accordance with the setting of a phrase symbol, a configuration may be employed in which music data of a phrase with the same or similar phrase symbol is not copied as necessary. . For example, a “copy prohibition switch” may be provided so that “copy prohibition” can be designated at any time in response to a user's operation of the switch, or using a command menu or the like in response to a mouse right-click operation or the like. For example, in the example of FIG. 3, even if the setting by the phrase symbol is set to be prioritized by a predetermined priority specifying switch or data, 1
"Copy prohibited" for all or part of the passage
By designating, the step S11 is not executed for the entire or a part of the section, so that the copying of the music data can be prohibited for the entire or a part of the section. In that case, for example, FIG.
A step for determining whether or not copying is prohibited is inserted between Steps S10 and S11 of the step "E."
If S, step S11 is jumped to step S9
(In this case, the music data of the copy-protected partial section is stored without being changed), or the process proceeds to step S5 or S6 (in this case, the music data of the copy-prohibited partial section) Is regenerated by the processing of steps S5 to S8). Such copy prohibition enables flexible melody generation when the generation of a plurality of sections is designated by the melody generation switch MS and when there is a phrase with the same or similar phrase symbol. In addition, it is possible to cope with a case where the user does not want to generate a melody by arbitrarily copying a melody to a phrase to which the same or similar phrase symbol is attached in the case of a phrase symbol priority. Alternatively, an inquiry may be made to the user as to whether or not to make a copy, and if the user refuses the copy, the copy may be prohibited so that the melody is not regenerated by copying.

Further, as another embodiment or modification,
Even when priority is given to the ON / OFF setting of the melody generation switch MS, if music data can be copied in accordance with a passage symbol, selection of whether or not to copy can be performed for each section. You may. For example, a "copy permit / prohibit switch" can be provided and the "copy permit / prohibit" can be designated at any time in response to a user's operation of the switch, or by using a command menu or the like in response to a mouse right-click operation or the like. You may do so. For example, in the example of FIG. 3, even if the setting of the melody generation switch MS is set to be given priority by a predetermined priority designation switch or data, all or one of the passages that can be copied in accordance with the passage symbol is selected. By designating "copy permitted" corresponding to the section of the set, the processing program is appropriately changed so that step S11 is executed for all or some of the sections without passing through the route of steps S5 to S8. do it.

Further, as another embodiment or modification,
Even in the case where priority is given to setting by a phrase symbol, the ON / OFF setting of the melody generation switch MS is taken into consideration, and
Copy music data only in the section where N is set, and
The music data may not be copied in the section where F is set. For this purpose, for example, a step of determining "is the currently processed section a generation section?" Is inserted before step S11 in FIG. 3, and if YES, step S1 is performed.
1 is executed, but if NO, the processing program may be appropriately changed so that step S11 is jumped to step S9.

In the above-described embodiment, the melody generation switch M for simply designating a section in which melody generation is performed.
S is provided for each section, and the melody generation switch MS is turned on.
The melody is composed by generating a rhythm (sound generation timing) and a pitch for each section based on the / OFF setting. However, when regenerating a melody, there are many cases where it is desired to regenerate the melody by changing only the rhythm of the melody or only the pitch of the melody. In such a case, regenerating the melody by changing both the rhythm and the pitch is not convenient because the melody rhythm or the melody pitch other than the change target is also changed. Therefore, a rhythm and pitch generation switch RPS (corresponding to the above-mentioned MS) is provided so that a melody can be generated by generating only the melody rhythm or only the melody pitch.
In addition, a plurality of rhythm only generation switches RS and pitch only generation switches PS may be provided for each section unit. That is, a rhythm only generation switch RS that specifies that only the rhythm is changed to regenerate the melody, or a pitch only generation switch PS that specifies that only the pitch is changed and the melody is regenerated.
May be provided separately from the rhythm and pitch generation switch RPS. FIG. 5 shows an embodiment in such a case. FIG. 5 is a conceptual diagram showing an embodiment in which a plurality of switches are provided for each section unit.

As can be understood from FIG. 5, in this embodiment, the rhythm and the pitch generation are performed in order from the left in the unit of the melody generated on the display 6A (here, for each phrase section which is the minimum unit of the melody generation). A plurality of switches such as a switch RPS, a rhythm only generation switch RS, and a pitch only generation switch PS are displayed. As described above, the melody can be classified into a plurality of section units, and the melody is generated for each section unit. Therefore, the rhythm and the pitch generation switch RPS, only the rhythm are generated for each section unit for which the melody is generated. A plurality of switches of the switch RS and the pitch only generation switch PS are displayed. Of course, the present invention is not limited to providing a plurality of switches for each phrase section as shown in this embodiment, and further, a plurality of switches for a longer passage section or a block section, and / or a plurality of shorter bar sections. May be provided. That is, as described above, a plurality of switches may be provided for each of a plurality of layers such as a phrase unit switch and a phrase unit switch. Also,
In this case, a predetermined priority order may be assigned to the switches in each layer as described above.

When the melody is regenerated with the rhythm and pitch changed by operating the rhythm and pitch generation switch RPS, the melody is reproduced in the same manner as when the melody generation switch MS is provided for each section described above. The description is omitted. Rhythm only generation switch RS
By operating, the melody is regenerated with only the melody rhythm as a change target. When the melody is generated by operating the rhythm only generation switch RS, if the rhythm and the pitch do not yet exist in the specified generation section, or if the rhythm only exists and the pitch does not exist,
One of the rhythms is selected from a database storing a plurality of rhythms according to the music genre and the like, and a rhythm (sound generation timing) is generated. In that case, for example, thereafter, a pitch generation process is performed by the generation switch PS only for the pitch described later, and a pitch is assigned to each hit point (sound generation timing) of the generated rhythm. On the other hand, when both the rhythm and the pitch are present in the designated generation section, the pitch is saved (partially or entirely) and only the rhythm is replaced. May be generated. When replacing the rhythm by storing the pitch, a rhythm having the same number of notes as the previous rhythm is selected from the database according to the genre and the like, and the stored pitch is assigned to the new rhythm in the same order as before. When replacing the rhythm while partially saving the pitch, the number of notes in the new rhythm may be different from the number of notes in the previous rhythm. If the new number of notes after the replacement is smaller than the stored pitch number, the pitch adopted from the earlier stored pitch is discarded. If the number of new notes after replacement is greater than the number of stored pitches, assign the stored pitches to the new rhythm in the same order as before and in chronological order,
The missing pitch is newly generated. In this case, the pitch is not limited to being allocated in the order of time from the front, but may be sequentially allocated from the back. On the other hand, even when there is a pitch, when a rhythm is generated without saving (discarding) the pitch, all existing pitches are discarded, and the above-mentioned pitch does not exist. As in the case, only the rhythm is newly generated. As described above, if it is possible to set whether or not only the melody rhythm is generated for each music generation section, it is possible to generate only the melody rhythm of a partial section again while preserving the melody pitch.

When the pitch only generation switch PS is operated, the melody is regenerated with only the melody pitch changed. When a melody is generated by operating the pitch only generation switch PS, a chord component sound is randomly assigned to an important sound and an insignificant sound is assigned to an insignificant sound among existing beats (toning timings) of the rhythm. To assign scale notes randomly. It should be noted that the scale sound may be randomly assigned to all the hit points without dividing into important sounds and non-important sounds. As described above, if it is possible to set whether or not only the melody pitch is generated for each music generation section, only the melody pitch of a partial section can be generated again while preserving the melody rhythm.

Any method of generating music data such as a melody may be used. As described above, it is possible to set whether or not to generate music data such as a melody for each predetermined partial section. Then, any music data generation method may be adopted regardless of the method of generating the music data itself. Also, a melody generation switch MS (or a rhythm and pitch generation switch RPS, a rhythm only generation switch RS, a pitch only generation switch PS, etc.)
Is not limited to a soft switch provided on the display of the display 6A, but may be a hardware switch. In this case, the switch may be used as another function. Also, when providing a plurality of switches,
Rhythm and pitch generation switch RPS, rhythm only generation switch RS, pitch only generation switch PS for each section
Although the example in which the types of switches are provided has been described, only switches for designating “generation (or not generation)” are provided for each section, and contents to be generated separately from the switches are “rhythm and pitch”, You may be comprised so that it can be selected by either "rhythm only" or "pitch only." A rhythm and pitch generation switch RPS, a rhythm only generation switch RS, and a pitch only generation switch PS are provided for each section.
Although the three types of switches described above are provided, the rhythm only generation switch RS and the pitch only generation switch PS can be set at the same time without providing the rhythm and pitch generation switch RPS. In such a case, "rhythm and pitch" may be generated.

As shown in FIG. 2, FIG. 4, and FIG. 5, a swelling line ML indicating a swelling state and a swelling state of a pitch in a section may be displayed corresponding to each section. The climax line ML is a line segment connecting the leading important hit point pitch and the last important hit point pitch in each passage, and represents a general change state of the pitch in each passage. This makes it easier for the user to determine the section in which the melody should be regenerated (or not regenerated). When the melody is generated in such a manner that one tune is generated by expanding the input motif, the position of the motif may be highlighted in the passage in which the motif exists. (In the illustrated example, it is indicated by a hatched square MT). This makes it easier for the user to determine the section in which the melody should be regenerated (or not regenerated). In addition, according to the same, similar, or non-similarity of each passage, a highlight M
The display mode of T (color, fill pattern, shape, etc.) may be made different. For example, "A" or "A '"
Sections are displayed in blue, sections "B" and "B '" are displayed in red, and so on.

The present invention can be applied not only for the purpose of partially modifying or regenerating a composed song, but also for automatically creating a new song. In this case, there is no need to perform a process of selecting a desired song to be changed before starting the process flow of FIG. 3 as in the case of the above embodiment,
The automatic music process is started from the process flow of FIG. In this case, the section to which the melody generation data supplied in step S1 of FIG. 3 is applied can be partially specified by the section specifying process in step S2. In other words, a partial section in which the melody generation data (first music condition) supplied in step S1 is prohibited from performing composition is specified in step S2. Thus, as a first step, a tune in which no tune data exists for a prohibited partial section is first created. Then, as a second stage, the music conditions supplied in step S1 and the setting contents of the generation section and the non-generation section in step S2 are changed (that is, the second music condition is set and the partial section to which the second music condition is applied) is changed. Is set), and the processing flow of FIG. 3 is executed again. For example, a section that has been created in the first stage is set as a non-generation section, and a section that has not been created is set as a generation section. In this way, by changing the music condition supplied in step S1 and the setting contents of the generation section and non-generation section in step S2 several times, the flow of FIG. 3 is performed several times to finally complete a desired music. According to this, song data can be automatically generated in a lump for discrete partial sections to which a common music condition can be applied,
At that time, automatic generation of music data can be surely prohibited in another partial section to which the music condition is not applied, so that efficient automatic music can be performed.

In the example of FIG. 3, the "music data generation processing portion according to the ON / OFF setting of the melody generation switch MS" (particularly, the portions of steps S5 to S8), that is, "first melody generation portion"
Generation means "and" a music data generation processing part according to the setting by a phrase symbol "(particularly, steps S10 and S11,
Further, step S used in the NO branch route of S10
5 to S8), that is, the “second generation unit” is mixed in one processing flow, but the present invention is not limited to this, and these “first generation unit” and “second generation unit” means"
May be clearly separated as separate processing flows, or may be separated as clearly separate hardware. Note that the present invention is not limited to the automatic tune of the melody music data as described in the above embodiment, but may be applied to the automatic tune of the accompaniment music data.

When the automatic musical composition apparatus is applied to an electronic musical instrument, the electronic musical instrument is not limited to a keyboard instrument, but may be a stringed instrument, a wind instrument, or a percussion instrument. Further, the present invention is not limited to the one in which the sound source device, the automatic music composition device, and the like are built in one electronic musical instrument main body, but each device is separately configured, and each device is connected using communication means such as a MIDI interface and various networks. Needless to say, the same can be applied to those that have been performed. In addition, a configuration including a personal computer and application software may be used. In this case, the processing program is stored on a magnetic disk,
It may be supplied from a storage medium such as an optical disk or a semiconductor memory, or supplied via a network. Further, the present invention may be applied to an automatic performance device such as a karaoke device or an automatic performance piano, a game device, a portable communication terminal such as a mobile phone, or the like. When applied to a portable communication terminal, not only when the specified function is completed only with the terminal, but also a part of the function is provided on the server side, and the specified function is realized as the whole system consisting of the terminal and the server You may make it.

When applied to an automatic performance device, the format of the performance data of the melody to be generated is "event + absolute time" format in which the event occurrence time is represented by the absolute time in a song or bar, and the event occurrence time "Event + Relative time" that represents the time from the previous event
Format, note pitch and note length, or rest and rest length, representing performance data in "pitch (rest) + note length" format, with memory area secured for each minimum resolution of performance However, any format such as a “solid” format in which events are stored in a memory area corresponding to the time at which a performance event occurs may be used. The processing method of the generated performance data at the time of automatic performance is a method of changing the processing cycle according to the set tempo, and the processing cycle is constant, and the method of counting the timing data in the performance data in one processing is determined by the tempo. Any method may be used, such as a method of changing according to the conditions. When performance data for a plurality of channels exists, a format in which data of a plurality of channels are mixed may be used, or a format in which data of each channel is separated for each track may be used.

[0046]

According to the present invention, the presence or absence of generation of music data such as a melody or accompaniment can be set for each partial section of a music piece, and only music data of a partial section of the music piece can be generated again. This makes it possible for the user to regenerate or generate music data that is easy for the user to use and that has a high degree of freedom, and that music data with a high degree of musical perfection can be generated by simple processing. can get.
Further, since the generation of music data is prohibited for the non-generation section, the music data for two or more generation sections separated by the non-generation section can be easily generated at the same time, which is efficient. In addition, since it is possible to specify which one of the music data generation processing based on the setting of the generation / non-generation of music data for each partial section and the music data generation processing based on a phrase symbol is given priority, the same / similarity of the phrase symbols is used. In addition to the song data generation process taking into account the above, it is also possible to freely create a song data by designating a partial section without reflecting the same / similarity of a phrase symbol. It is also possible to regenerate the music data of some sections while reflecting the same / similarity of the symbols.

Further, by giving priority to the music data generation processing based on the phrase symbols, for example, music data of the same phrase symbols as the section in which the music data has already been created can be easily generated by copying. Musically reliable self-playing songs can be easily performed, while
In a section in which the preceding section of the same section symbol does not exist, music data generation is performed by music data generation processing based on the setting of whether or not music data is generated for each partial section, thereby regenerating music data with a degree of freedom or Generation is possible. In this way, it is possible to regenerate or generate music data that is easy for the user to use and has a high degree of freedom, and it is also relatively easy to compose a melody with high musical perfection.
