Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic music composition apparatus for composing music by inputting music composition conditions for each passage. The present invention relates to a recording medium on which software that configures the automatic music composition device by executing the program is recorded.

[0002]

2. Description of the Related Art Conventionally, various automatic melody generating apparatuses for performing automatic music have been proposed in order to reduce the burden on a composer. As an automatic melody generation device of this kind, the present applicant has proposed an automatic melody generation device for automatically generating a melody based on a music template (the specification attached to Japanese Patent Application No. 8-132208 and See drawing). In this automatic melody generation device, a song template that matches the song composition condition is searched and selected from a plurality of song templates stored in advance based on the song composition condition set by the user, and the song template selected as necessary is selected. A melody is generated using the modified, searched and modified song template. The “song template” is a melody template that stores a pitch pattern and a rhythm pattern for one song, and has composition conditions hierarchized in the order of the entire song, phrases, phrases, and bars from the top.

In the above-mentioned automatic melody generating apparatus, the composition condition is that the genre of the music (for example, 8
Beats), melodic (flowing melody) / rhythmic (chopping melody), tempo, range width, number of passages, etc. Is used. Of course, appropriate composition conditions are set for phrases and measures.

[0004]

By the way, in the conventional automatic melody generating apparatus, the input operation of the composing condition by the user at the time of composing or generating the music template is independent for each passage. In other words, the phrases to be input for the composition conditions are designated one by one, and the user inputs the composition conditions for each phrase, and therefore, the phrase having the same or similar phrase as the phrase in the already entered phrase is entered. At the time of inputting the passage, the already entered composition conditions had to be re-input.

[0005] As one method for systematically expressing the relationship between phrases to improve the efficiency of composition work, a method of assigning the same or similar phrase symbols to a plurality of phrases having the same or similar phrases is known. Although it is conceivable, as described above, the input operation of the composition conditions is independent for each passage, so that the passage symbol is assigned independently for each passage. In other words, the task of ensuring the consistency of the phrase symbols in the entire music must be a burden on the user. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide an automatic music composition apparatus and a recording medium that can reduce the time required for music composition work.

2. Operation of Embodiment Next, the operation of the automatic music composition device having the above-described configuration will be described. The automatic music composition device according to the present embodiment selects a “song template” according to lyrics and other music conditions (composition conditions), and automatically generates a melody based on the music template. The data structure of the song template is arbitrary, but here, Japanese Patent Application No. 8-132
As disclosed in the specification and drawings attached to the patent application No. 208, lyrics, composition conditions, melody data, and the like are arranged in a hierarchy in the order of the whole music, a passage, a phrase, and a bar. .

More specifically, the composition conditions such as the genre of the music (for example, 8 beats), melodic / rhythmic, tempo, width of the range, the number of passages, etc., for the entire song, are set for the passage. , The number of phrases in the section, the set of the start code and end code of the passage, etc. are hierarchized. A phrase symbol (for example, A, B, A ', A ", etc.) indicating the format of the phrase is assigned to each phrase, and the phrase portions have different alphabet parts (for example, A and B). Indicates that the phrases are completely different, that is, the lyrics and composition conditions are completely different, and the phrases having the same alphabet portion but different numbers of dashes (for example, A, A 'and A ") are similar. Indicates a slightly different passage, that is, a passage having many lyrics and composition conditions in common.

2-1. Music Composition Operation Here, composition processing using the above-described music template will be described. However, processes that are not directly related to the present invention, such as inputting composition conditions for the entire music, are simplified or omitted in order to avoid complications.

FIG. 2 is a flowchart showing the flow of the passage data input processing and the melody generation processing by the automatic music composition apparatus according to the present embodiment, and is shown in FIGS.
4 is a diagram showing an editing screen displayed by the display circuit 5, respectively. The phrase data is data associated with each phrase such as a phrase symbol and composition conditions, and the generated melody is also included in the phrase data.

As shown in FIG. 2, in the process of inputting phrase data, first, the user operates the pointing device 8 to designate a phrase for inputting phrase data, thereby selecting the phrase (step SA1). . Next, the user operates the keyboard 7 to input a phrase symbol and composition conditions, and associates them with the selected phrase (step SA).
2, SA3). For example, in FIG. 3, by pointing a passage number field 511, a passage symbol field 521, or a composition condition field 531 of the first passage by a pointer (cursor) (not shown), the first passage is selected and the designated field is indicated. Can be entered.

The processing of steps SA1 to SA3 is performed until all the required phrases are associated with the phrase symbols and composition conditions. Note that it is possible to delete the selected phrase or insert a new phrase immediately before or immediately after the selected phrase. When inserting / deleting a phrase, the phrase number is automatically reset. It is also possible to correct the phrase symbol and composition conditions of the selected phrase.

When the phrase symbols and composition conditions have been associated with all the required phrases, and the user operates the keyboard 7 or the pointing device 8 to input predetermined data (melody generation command), the melody generation process is started. (Step SA4). As the melody generation processing, the processing disclosed in the specification and the drawings attached to the patent application of Japanese Patent Application No. 8-132208 can be adopted.
That is, the automatic music composition apparatus according to the present embodiment searches and selects a music template that matches the music composition conditions set in steps SA1 to SA3, and directly processes or processes the melody pattern or pitch pattern and rhythm pattern of the selected music template. Generate The generated melody is
Each melody section corresponding to each phrase is stored in a memory area corresponding to each phrase as a part of the phrase data (step SA5).

FIG. 10 is a diagram conceptually showing a storage state of each phrase data on the RAM 2. As shown in FIG. 10, the phrase data relating to the first phrase (first phrase data) and the phrase data relating to the second phrase are shown. (2nd phrase data), ... is RA
They are sequentially stored on M2. As is clear from the figure, each phrase data is composed of a phrase symbol, a composition condition, and a generated melody.

2-2. In the present embodiment, in order to reduce the burden on the user, the following three processes (functions) are performed in the process of inputting the phrase data in steps SA1 to SA3 in FIG. Is provided.

2-2-1. Copy & Paste Processing (Function) FIG. 11 is a flowchart showing the flow of copy & paste (copy) processing performed in the passage data input processing. As shown in this figure, the user operates the pointing device 8 or the like. Then, the phrase symbol of the copy source phrase is designated (step SB1), and a predetermined trigger is given by pressing the copy key of the keyboard 7, etc., so that the phrase symbol of the copy source phrase and the composition conditions are stored in the RAM 2. The data is copied to a temporary storage area (for example, a clipboard) (step SB2).

Next, the user operates the pointing device 8.
Is operated to specify the phrase to be pasted (step SB3), and a predetermined trigger is given, for example, by pressing the paste key of the keyboard 7, thereby generating the phrase symbol stored in the temporary storage area on the RAM 2. And the composition conditions
The data is written to the area on the RAM 2 corresponding to the specified passage to which the paste is to be made (step SB4). The phrase symbols and composition conditions thus pasted are displayed in step SB5 so that the user can view them.

Specifically, for example, in FIG. 3, the user operates the pointing device 8 to select the phrase symbol field 521 of the first phrase, and presses the copy key of the keyboard 7 in this state. The phrase symbol "A" in the selected phrase symbol field 521 and the composition condition A in the composition condition field 531 associated with the phrase symbol field 521 are copied to a temporary storage area on the RAM 2 and used. The user operates the pointing device 8 to enter the phrase symbol field 52 of the third phrase.
3 and pressing the paste key of the keyboard 7 in this state, as shown in FIG. 4, the phrase symbol "A" copied to the temporary storage area and the composition condition A
Is displayed in the phrase symbol field 523 and the composition condition field 533 of the third phrase.

As described above, since the phrase symbols and the composition conditions can be duplicated by a simple operation, it is possible to easily create a phrase having the same composition conditions as those for which the composition conditions have already been input. In addition, if the phrase symbol and composition conditions of the paste destination phrase are corrected after the copy and paste, it is possible to easily create a phrase having composition conditions similar to those in which the composition conditions have been input.

The method of implementing copy and paste is arbitrary, and may be implemented by, for example, so-called drag and drop. The method of selecting the phrase to be copied is arbitrary, and a search may be performed using the phrase symbol as a key, and the hit phrase may be selected. Of course, the fields specified when selecting the source and destination phrases are
It may be either a phrase symbol field corresponding to the relevant phrase or a composition condition field.

2-2-2. Composition Compensation Condition Correction Process (Function) FIG. 12 is a flowchart showing a flow of composition composition condition modification process performed in the passage data input process. The process shown in FIG. 12 is divided into cases by referring to FIGS. This will be specifically described.

(1) In the state shown in FIG. 5, when the composition condition of the fifth section is corrected. In this case, the user specifies the fifth section for which the composition condition is to be modified and the composition condition of the section is specified. When the composition condition A in the field is corrected and a specific instruction is input using the keyboard 7 or the pointing device 8 to reflect the correction result (step SC1 in FIG. 12), the same as the fifth phrase to be corrected is performed. It is determined whether or not the phrase with the phrase symbol exists ahead (in the direction to the first phrase) (step SC2).

In this case, the phrase symbol of the fifth phrase to be corrected is "A" and the phrase symbols of the first, third, and fourth phrases are "A". The result of the determination is "YES", and it is further determined whether or not a phrase having the same phrase symbol as the fifth phrase to be corrected is located backward (toward the eighth phrase) (step SC3). In this case, the result of the determination in step SC3 is "NO", so that the area on the RAM 2 corresponding to the fifth phrase is
A phrase symbol in which a dash symbol "'" is added to the phrase symbol of the fifth phrase and a modified composition condition (modified composition condition A') are written (step SC6).

Then, it is determined whether or not a phrase having the same phrase symbol as the phrase symbol to which "'" has been added by the immediately preceding process exists after the fifth phrase to be corrected (step SC7). In this case, since there is no phrase having such a phrase symbol after the fifth phrase, the result of the above determination is "NO". As a result, as shown in FIG. 6, the contents on the RAM 2 including the modified composition condition A 'and the fifth phrase having the phrase symbol "A'" are displayed by the display circuit 5 (step SC10).

(2) In the state shown in FIG. 6, when the composition condition of the first phrase is corrected In this case, the user designates the first phrase for which the composition condition is to be modified and the composition condition of the phrase is specified. When the composition condition A in the field is modified to the modified composition condition A2 and the modification result is to be reflected (step SC1), the first modification target is modified.
It is determined whether or not a phrase with the same phrase symbol as the phrase exists ahead (step SC2).

In this case, since the first phrase is the first phrase, the above determination result is "NO". That is, the first
It is not necessary to correct the phrase symbol of the phrase. And
In a succeeding step SC9, a correction process of a phrase following the first phrase is performed. Specifically, in step SC9, among the phrases located after the first phrase to be corrected, the phrases having the same phrase symbol as the first phrase (in this case, the third and fourth phrases having the phrase symbol "A") The modified composition condition A2 is written in an area on the RAM 2 corresponding to the composition condition of (4 phrases). As a result, as shown in FIG. 7, it is displayed that the composition conditions of the first, third and fourth passages have been changed to the modified composition conditions A2 (step SC10).

(3) In the state shown in FIG. 7, the case where the composition condition of the third passage is corrected In this case, the user designates the third passage for which the composition condition is to be modified and the composition condition of the passage is specified. When the composition condition A2 in the field is modified to the modified composition condition A3 and the modified result is to be reflected (step SC1), it is determined whether or not a phrase with the same phrase symbol as the third phrase to be modified exists ahead. Is determined (step SC2).

In this case, since the phrase symbol of the third phrase is "A" and the phrase symbol of the first phrase ahead is "A", the determination result of step SC2 is "YES". Next, it is determined whether or not a phrase having the same phrase symbol as the third phrase to be corrected exists behind (step SC3). In this case, since the fourth phrase having the phrase symbol “A” exists, the above determination result is “YE
S ", and it is determined whether or not the corresponding phrase (the fourth phrase) is also to be corrected (step SC4).

This determination is made based only on the preset correction mode. The correction mode here means that when it is necessary to modify the composition conditions of a certain phrase and change the phrase symbol of the phrase, not only the phrase symbol and composition conditions of the phrase, but also the phrase after the phrase. This indicates whether or not to change the phrase symbol and composition conditions of the phrase having the same phrase symbol as those described above, and can be arbitrarily set by the user. The correction mode is not limited to be set in advance, and in step SC4, the user may be allowed to select whether or not to set the correction mode.

In the case of the correction mode in which the phrase symbols and composition conditions of the following passage are also changed. Here, it is assumed that the correction mode is a mode in which the phrase symbols and composition conditions of the subsequent passage are also changed, and the judgment in step SC4 is made. The result shall be “YES”. As a result, of the passages after the third passage to be corrected, the passage having the same passage symbol “A” as the passage symbol of the third passage (the third passage)
The phrase symbol "A '" obtained by adding "'" to the phrase symbol "A" common to each phrase is written in the area on the RAM 2 corresponding to the phrase symbol of the fourth and fourth phrases).
The modified composition condition A3 is written in the area on the RAM 2 for the composition condition of the passage.

Next, it is determined whether or not a phrase having the same phrase symbol "A '" as the phrase symbol to which "'" has been added by the immediately preceding process exists after the third and fourth phrases. (Step SC7). In this case, since the phrase symbol of the fifth phrase is “A ′”, the determination result is “YE”.
S ”, and in step SC8,“ ′ ”is added to the phrase symbol“ A ′ ”of the corresponding fifth phrase, and the corresponding R
It is written to the area on AM2. If there are a plurality of clauses having the same clause symbol as the clause symbol to which the above-mentioned “′” is added, “′” is added to the clause symbols of all the corresponding clauses. Then, it is determined whether or not the phrase symbol "A""exists behind the fifth phrase (step SC7). That is, steps SC7 and SC8 are repeated until there is no phrase having the same phrase symbol after the corresponding phrase. In this case, when the phrase symbol of the fifth phrase becomes "A", the determination result of step SC7 becomes "NO". As a result, as shown in FIG. The phrase symbol is changed to "A '" and the composition conditions are changed to the modified composition condition A3.
Is displayed, and that the phrase symbol of the fifth phrase has been changed to "A" (step SC10).

In the case of the correction mode in which the phrase symbols and the composition conditions of the subsequent phrase are not changed On the other hand, in the case where the preset correction mode is the mode in which the phrase symbols and the composition conditions of the subsequent phrase are not changed, the flow proceeds to step SC4. The determination result is "NO", the phrase symbol "A '" is written in the area on the RAM 2 for the phrase symbol of the third phrase to be corrected, and the corrected composition is written in the area on the RAM 2 for the composition condition of the third phrase. The condition A3 is written.

Next, in the phrases following the phrase whose phrase symbol is to be corrected, the above-mentioned steps are repeated until there is no phrase having a phrase symbol obtained by adding "'" to the phrase symbol of the phrase whose phrase symbol is to be corrected. Similar processing is performed (steps SC7 to SC8). As a result, as shown in FIG.
It is displayed that the phrase symbol of the third phrase is changed to "A '", the composition condition is changed to the modified composition condition A3, and that the phrase symbol of the fifth phrase is changed to "A" (step SC).
10).

2-2-3. FIG. 13 is a flowchart showing the flow of a phrase symbol correction process performed in the phrase data input process. The process shown in this diagram will be specifically described with reference to FIGS. 4 and 14. I do.

As shown in FIG. 13, the user designates a third phrase (see FIG. 4) whose phrase symbol is to be modified, and changes the phrase symbol "A" in the phrase symbol field of the phrase to the modified phrase symbol "A". A '", when the user inputs a specific instruction using the keyboard 7 or the pointing device 8 to reflect the correction result (step SD1), the area on the RAM 2 for the phrase symbol of the third phrase is stored in the RAM 2. The modified phrase symbol "A '" is written (step SD2).

As a result, as shown in FIG. 14, it is displayed that the phrase symbol of the third phrase has been modified to the modified phrase symbol "A '" (step SD3), and the composition conditions of the third phrase are modified. A warning message prompting is displayed (step SD4).
The warning method is optional, but if a new window is opened and a warning text is displayed as shown in FIG.
The user's attention can be reliably raised. On this occasion,
If a sound is produced at the same time, a further effect can be obtained. The window may be closed when the user inputs a predetermined instruction, or may be automatically closed after a predetermined time.

3. Conclusion As described above, according to the present embodiment, it is possible to easily duplicate the phrase symbols and the composition conditions, so that the composition conditions for the phrases having the same composition conditions or similar composition conditions as the already input phrases can be obtained. Data input can be facilitated. In addition, the phrase symbols are appropriately modified in conjunction with the modification of the composition conditions, so that the user can reduce the labor required for managing the phrase symbols and can accurately and clearly express the relation of each phrase. it can. In particular, for similar phrases, the number of dashes increases toward the rear, which is advantageous in that it is easy to grasp the configuration of the entire music. Of course, the number of dashes may be increased in the order of correction to make it easier to comprehend the composition history. In this case, in FIG. 8, which is a result of correcting the third phrase, the phrase symbols of the third and fourth phrases are used. Is "A"", and the phrase symbol of the fifth phrase is" A '". Further, since the user is warned when the correspondence between the phrase symbols and the composition conditions is likely to be broken, the labor required for the user to maintain the correspondence can be reduced.

In the above-described embodiment and its modifications, the physical storage format of the phrase symbols and composition conditions on the RAM 2 is arbitrary, and the correspondence with each phrase is logically clear. I just need. In the phrase symbol correction processing, a warning may be issued only when a phrase having the same phrase symbol as the phrase symbol before correction is present ahead. Furthermore, in the phrase symbol correction processing, if there is a phrase having the same phrase symbol as the corrected phrase symbol, the user is encouraged to unify the composition conditions or to correct the revised phrase symbol again. Is also good. Further, the correction of the composition conditions and the phrase symbols may be performed before or after the melody is created and stored (steps SA4 and SA5 in FIG. 2). When the melody is performed later, the melody may be automatically generated and stored again in accordance with the corrected composition conditions and the phrase symbols, or a warning may be issued to the user to prompt the user to correct the melody. .

4. Modification Next, a modification of the above-described embodiment will be described with reference to FIGS. The automatic composition device according to the present modification has the configuration shown in FIG. 1 as in the above-described embodiment.

FIG. 15 is a diagram conceptually showing the storage state of each phrase data on the RAM 2. As is clear from this figure, the present modified example is different from the above-described embodiment in that the phrase data contains lyrics. It is a point that includes. That is, in this modified example, not only the composition conditions but also the lyrics are input in step SA3 in FIG. In general, for lyrics, it is not necessary to match between the phrases, so that the composition condition correction processing and the phrase symbol correction processing are the same as the processing described in the above embodiment. Therefore, here
Only copy and paste processing different from the above-described embodiment will be specifically described with reference to FIGS.

4-1. Copy and Paste Process (Function) of Modification Example FIG. 16 is a flowchart showing the flow of copy and paste processing in the modification example. FIGS. 17 to 19 are editing screens displayed by the display circuit 5 in this modification example, respectively. FIG. As shown in FIG. 16, the user designates the first phrase (see FIG. 17) of the copy source by operating the pointing device 8 or the like, and gives a predetermined trigger by pressing the copy key of the keyboard 7 or the like. Accordingly (step SE1), it is determined whether or not not only the phrase symbols and the composition conditions but also the contents (lyrics) of the lyrics field 541 are to be copied (step SE2). This determination is made in accordance with a copy and paste mode set in advance or by a specific operation at the time of trigger input (for example, pressing a copy key while pressing a shift key). Here, when the copy key is pressed while the shift key is pressed, the mode is a mode in which the lyrics are also copied and pasted (hereinafter referred to as a lyrics mode), and when only the copy key is pressed, only the passage symbols and the composition conditions are copied. It is assumed that a mode for pasting (hereinafter referred to as a normal mode) is set. It should be noted that the present invention is not limited to setting the copy & paste mode in advance, and may set whether or not to copy the lyrics at the time of the copy & paste operation.
The operator may be warned to make the setting.

(1) Lyrics Mode In the lyrics mode, the result of the judgment in step SE2 is “YE
S ", the phrase symbol" A ", the composition condition A, and the lyrics A of the first phrase of the copy source are copied to a temporary storage area (for example, a clipboard) in the RAM 2 (step SE).
3). Then, the user designates the third phrase to be pasted (step SE4) and gives a predetermined trigger by pressing the paste key of the keyboard 7 or the like, whereby the RAM is given.
The phrase symbol "A", the composition condition A, and the lyrics A stored in the temporary storage area on the RAM 2 are written in the area on the RAM 2 corresponding to the third phrase to which the paste is made (step SE).
5) As shown in FIG. 18, it is displayed that the phrase symbol "A", the composition condition A, and the lyrics A have been pasted into the third phrase (step SE6).

(2) Normal Mode In the normal mode, the result of determination in step SE2 is “YE
S ", the phrase symbol" A "of the first phrase and the composition condition A of the copy source are copied to a temporary storage area (for example, a clipboard) on the RAM 2 (step SE7). Thereafter, the processing of steps SE4 to SE6 described above is performed,
As shown in FIG. 19, it is displayed that the phrase symbol "A" and the composition condition A have been pasted to the third phrase. In addition,
In step SE5, even when there are only phrase marks and composition conditions on the clipboard, lyrics (in this case, a character string having a length of 0) may be written, or only the phrase symbols and composition conditions may be written. Is also good.

As described above, in this modification, not only the phrase symbols and composition conditions, but also the lyrics can be copied and pasted, so that the burden on the user in the process of inputting the phrase data can be further reduced. it can. Further, since it is possible to select whether or not to copy and paste the lyrics, the degree of freedom is high, and by selecting an appropriate process, the input efficiency of phrase data can be further improved.

As for the lyrics, similarly to the composition condition, a function for automatically matching the data may be added, and the user may selectively use the function. In addition, the example in which the lyrics mode is set by pressing the shift key at the same time as the copy key has been described.
The copy and paste in the lyrics mode may be performed by dropping, or the copy and paste in the lyrics mode may be performed by dragging and dropping the lyrics field. Of course, it goes without saying that keys other than the shift key may be used.

5. Supplement In the above-described embodiments and modified examples, examples in which the present invention is realized by a general-purpose computer have been described. In the form of an electronic musical instrument, for example,
The keyboard, various switches, and the like perform the same functions as the above-described keyboard and pointing device.

As described above, according to the present invention, it is possible to copy a phrase symbol and a composition condition of a source phrase into a destination phrase, thereby reproducing the phrase having the same phrase repetition. For, the phrase symbols and composition conditions of the phrase that have already been input can be easily diverted. Therefore, it is possible to reduce the labor required for inputting the phrase symbols and the composition conditions.
1).

Further, since the composition conditions can be modified, it is possible to reduce the labor required for inputting a phrase having a repetition of a similar phrase (claims 2, 6, 7, and 8). In addition, the 1
Since the phrase symbols or the composition conditions are corrected so that there is no inconsistency in the one-to-one correspondence, the consistency of the input data is reliably maintained, and the burden on the user can be reduced. , 4,6,7). Further, when the phrase symbol is corrected by the user, the user is urged to correct the composition conditions corresponding to the phrase symbol, so that high reliability can be maintained with respect to the consistency of the input data. 5, 8).

Further, since not only the phrase symbols and the composition conditions but also the lyrics can be duplicated, it is possible to further reduce the time and effort required for inputting a phrase having a repetition of the same phrase. Item 9). Furthermore, since it is possible to set whether or not to include the lyrics in the object of duplication, the user can copy the “first and second choruses” including the lyrics when duplicating “the same phrase is repeated”. An optimal duplication operation can be selected according to the situation, such as not including lyrics at times (claim 10).

After all, as is clear from the above,
According to the present invention, music composition conditions and the like can be input with a simple operation, so that it is possible to reduce the burden (load) on the user in music composition work.
