[Music generation data and vocabulary / sentence data]
In the songwriting / composition processing system according to one embodiment of the present invention, the songwriting / composing process of the first to third embodiments described later in [1] to [3] is executed, and the music generation data and the vocabulary / sentence data are obtained. To compose a desired song. FIG. 2 shows a configuration example of music generation data used in the songwriting system according to an embodiment of the present invention, and FIG. 3 shows a configuration example of vocabulary / sentence data used in the system.

In the music generation database constructed in the ROM 2 or the external storage device 4 of this system, music generation data is recorded as a template. FIG.
As shown on the left side, each music generation data includes a melody generation data and an accompaniment generation data and is assigned a genre, and the melody generation data and the accompaniment generation data have contents corresponding to the genre. Has become. For example, in the genre of “love ballad”, the number of notes is small, and the accompaniment style is the ballad style.
In the genre of "minor enka", the chord progression is a minor chord progression.

As shown in the center (upper part) of FIG. 2, the melody generation data is composed of music composition data, rhythm characteristic data, pitch characteristic data, chord progression data, and the like. First, as shown on the right side of FIG. 2, the music composition data includes block configuration data, phrase configuration data, phrase configuration data, and the like, and the number of blocks, phrases, and phrases is defined. The block configuration data may be, for example, “Music is“ A block ”and“ B block ”
The phrase configuration data represents, for example, "the song is composed of four phrases," the phrase a "-" the phrase b "-" the phrase a '"-" the phrase c ". And the phrase configuration data represents a phrase configuration such as "each phrase is composed of two phrases".

The rhythm characteristic data is composed of basic note length data and note number data, information indicating the presence or absence of syncopation, and the like. It is used as instruction data. The basic note length data represents the note length of a basic note in a block, a phrase, or a phrase, for example, “eighth note” or “1”.
The maximum number of notes per block, phrase, or phrase is defined accordingly. The number-of-notes data indicates the number of notes (frequency of notes) in each block, each passage or each phrase by the number of notes relative to the maximum number of notes. The range of the number of notes is defined by “place”, “small eyes” and the like.

The pitch feature data is composed of a range, dynamics and the like (not shown), and the chord progression data is a string of chord names (including time data if necessary).

The accompaniment generation data is shown at the center (lower part) in FIG.
As shown in (1), the data comprises chord progression data and style designation data, and the chord progression data is used in common with the melody generation data. The style designation data is data for designating any of a large number of separately stored accompaniment style data. The accompaniment generation data may include other data.

On the other hand, the vocabulary / sentence database constructed in the ROM 2 or the external storage device 4 of this system is:
As illustrated in FIG. 3, a vocabulary or a short sentence (right side) to be lyrics is divided by a minimum of M syllables to a maximum of N syllables (left side). It is a database of sentences. The division of the number of syllables is indicated based on the melody generation data [tune composition data and rhythm characteristic data (maximum pitch data and note number data)] in generating the lyrics, and the vocabulary and vocabulary belonging to the specified division are specified. An appropriate vocabulary / sentence is selected from the sentences by a predetermined method.

As shown on the right side of FIG. 3, vocabulary / sentence data representing vocabulary / sentences corresponding to the syllable number is stored in each syllable number section. "Genre" data indicating whether the syllables can be used, "Modified example" data for slightly increasing or decreasing the number of syllables, and the like are stored.

The genre data indicates the approximate contents of the lyrics in a song genre, and is used to select lyrics suitable for the genre. For example, in "all genres", there are many words that represent general scenes, and in "love songs", many words that show the affection of men and women appear.

The modified example data is class data of the vocabulary / sentence data in which particles are inserted or deleted or replaced with other words having a similar meaning, and the number of syllables is slightly increased or decreased from the original vocabulary or sentence. Let me. The modified example data is used to increase or decrease the number of syllables in the lyrics in a third embodiment described later.

[1] Lyrics Composition Process of First Embodiment FIG. 4 is a functional block diagram of the lyric composition process of the first embodiment executed by the lyric composition system according to one embodiment of the present invention. Here, the outline of the songwriting function according to each embodiment will be described very simply with reference to FIG. In the songwriting system according to one embodiment of the present invention, common melody generating data is used to generate a melody and lyrics.

In the first embodiment, the melody and the melody generation data which are the basis of the lyric generation are obtained from the tune generation database A1 via the tune generation data selection unit A3 through the lyric generation unit A4 and the melody generation unit (1). ) A5, and the lyrics and the melody are generated based on the music generation data. The number of notes of the melody generated by the melody generation unit (1) A5 is corrected by the melody correction unit A6 so as to match the number of syllables of the lyrics generated by the lyrics generation means A4. Consistency is achieved.

In the second embodiment, a melody generating unit having a function of matching the generated melody with the number of syllables of the lyrics instead of the melody generating unit (1) A5 and the melody correcting unit A6 of the first embodiment. (2) is provided (FIG. 1)
0). Furthermore, in the third embodiment, a lyric correction unit is provided in place of the melody correction unit A6 of the first embodiment, and the number of syllables in the lyrics is corrected to match the number of notes in the melody (FIG. 12).

Now, the first embodiment will be described in more detail with reference to FIG. As described above, the music generation database A1 and the vocabulary / sentence database A2 store the music generation data and the vocabulary / sentence data, respectively. The music generation data selection unit A3 selects music generation data (template) stored in the music generation database A1 according to the genre designated by the user, etc., and, together with the genre data corresponding to the music genre,
Among the melody generation data, music composition data indicating the number of phrases, etc., the number of notes (some data of notes) and 1
Rhythm feature data or the like defining the maximum number of notes of a phrase (determined by basic tone length data) is sent to the lyrics generation unit A4, and music composition data, rhythm feature data, pitch feature data, chord progression data and the like are transmitted to a melody generation unit. (1) Send to A5.

[Generation of lyrics data] First, the lyrics generation unit A4
Then, based on the music composition and rhythm characteristic data of the music generation data, the vocabulary / sentence data of the vocabulary / sentence database A2 is referred to, and vocabulary / sentence candidates to be assigned to each phrase are extracted according to the genre data. . The extracted data is displayed on the display 14 and presented to the user. Therefore, the user can select any vocabulary
When a sentence is selected, lyrics data representing the selected vocabulary / sentence is generated. The lyrics data generated in this case may be randomly selected on the system side from the extracted vocabulary / sentence candidates. Further, the user may be able to edit the vocabulary / sentence of the lyrics data as needed.

FIG. 5 shows an example in which lyrics data is generated when a syllable (character) number is specified for each block with a song structure of two blocks and four phrases. Hereinafter, the procedure for generating lyrics data will be described with reference to this example. In the song generation data selection unit A3, the leftmost “block” to
"A block" as indicated by "data for generation"
And music composition data representing the music structure with eight blocks of “first block” to “eighth phrase”, two blocks of “B block”, four phrases of “first phrase” to “fourth phrase”,
Melody generation data having rhythm characteristic data in which the basic pitch and the frequency of the number of notes are specified for each of the blocks A and B are selected together with the genre data specifying the music genre, and sent to the lyrics generation unit A4.

The lyric generation unit A4 first calculates lyric generation conditions relating to the number of syllables (characters) based on the transmitted music generation data (genre data, music composition data, and characteristic data). In other words, based on the number of phrases obtained from the music composition data and the rhythm feature data, the maximum number of notes of one phrase (depending on the basic pitch), the number of notes (frequency), and the like, the fifth row in FIG. As described above, the maximum number of syllables and the number of syllables (characters) for each phrase are calculated as lyric generation conditions, and the calculated lyric generation conditions are used as syllable (character) number indication data for the lyrics candidates.

For example, when the basic note length is designated as "eighth note" as in the block A in FIG. 5, the maximum number of syllables is set to "maximum 16 syllables" (FIG. 5: fifth stage). ("Lyrical condition") right side]. For the number of syllables (characters),
The number of notes corresponds to “small”, “middle” and “large” of data, respectively, and “small” = 1-7 syllables (characters), “medium” = 8-12 syllables (characters), respectively. ) And the range of “more” = 13 to 16 syllables (characters) are automatically selected. In the example of FIG. 5, since the data of the number of notes in the A block is somewhat “small”, as shown to the left of the fifth row (“lyric generation condition”), the number of characters “small” (= 1 to 7 syllables) A range is selected. Then, the number of syllables (characters) randomly determined from the range selected according to the content of the data to some extent is the syllable for the lyrics of each phrase (first to fourth phrases) in the block (A block). This is a condition for generating a (character) number.

When the basic note length is specified as "sixteenth note" as in the B block, the maximum number of syllables is set to "maximum 32 syllables" (FIG. 5: fifth stage (" Lyric generation condition ") right side]. As for the number of syllables (characters), the number of notes is slightly smaller, middle, and larger.
, "Medium" = range of 15 to 24 syllables (characters) and "medium" = range of 25 to 32 syllables (characters), respectively. Is automatically selected. In the example of FIG. 5, since the data of the number of notes is somewhat “middle”, the number of characters “middle” [= 15 to 24 syllables (characters) as shown on the right side of the fifth row (“lyric generation condition”) ] Range is selected. The number of syllables (characters) randomly determined from the range selected according to the content of the data to some extent is the syllable for each phrase (the fifth to eighth phrases) in the block (B block). This is a condition for generating a (character) number.

Next, a vocabulary / sentence which satisfies the lyric generation condition (syllable number instruction data) calculated in this way and satisfies the music genre specified by the genre data is obtained from the vocabulary / sentence database A2. Searched and extracted. When there are a plurality of extracted vocabularies and sentences, as described above, the vocabulary and sentences are selected by the user from the vocabulary and sentences or randomly selected by the system, and the selected vocabulary and sentences are each phrase. Are sequentially generated as lyrics data. 5 ("Lyrical example")
Shows an example of the lyrics generated in this way, and the parentheses indicate the number of syllables (characters) for each phrase of the generated lyrics.

[Generation and modification of melody data]
The melody generation section (1) A5 generates melody data based on the melody generation data of the music generation data. For example, the number of notes in the melody data is determined at random according to the number of notes, the number of notes represented by the data, the maximum number of notes in one phrase defined from the maximum length data, and the like. Here, the data relating to the number of notes is similar to the number of syllables of the lyrics because the original melody generation data is also used in the lyrics generation unit A4, but does not completely match due to the presence of random elements. . Therefore, the correction of the mismatched melody part is performed by the melody correction unit A6.
It is left to the function of.

On the other hand, the melody modifying unit A6 increases or decreases the number of notes in the melody data generated by the melody generating unit (1) A5 according to the number of syllables of the lyric created by the lyric generating unit A4. A process for correcting the melody data is performed, and this melody correction process is referred to as "matching the melody to the lyrics". This "matching of melody to lyrics" process is not a process of generating a new melody,
In principle, the number of notes is simply increased or decreased based on the melody already generated by the melody generation unit (1) A3.

That is, the following matching rules (a) and (4) are applied to the lyrics data generated by the lyrics generation unit A4.
By applying (b), the number of melody notes is adjusted (increased / decreased) in accordance with the number of notes in the melody data and the number of syllables in the lyrics data: (a) When the number of notes> the number of syllables (characters) Priority is assigned to the type of notes (dots) to be reduced. For example, a priority order such as priority = “other> chord constituent sound> strong beat> phrase end> phrase start” is set. To delete notes (dots). Basically, the deleted note is set as a rest, but the length of the note immediately before the deleted note may be extended as necessary. If there are many notes of the same rank as deletion candidates, a note to be deleted is selected at random from these notes. (B) In the case of the number of notes <the number of syllables (characters): ・ Duplicate the sound length and add the same sound. For example, one quarter note is divided into two eighth notes of the same pitch. -The rest part is filled with the note immediately before or after the rest. And so on.

FIG. 6 shows an example of melody data correction by the "matching of melody to lyrics" process. For example, assuming that the first phrase of the melody is generated as shown in FIG. 6A, the number of notes is five, and the lyrics corresponding to this phrase are “shadow shakes” (lower in FIG. 6B).
Less than 7 syllables. Therefore, the matching rule (b)
Need to be applied to add two. In this example,
As shown in (1), the original half note is divided into two to add a quarter note, and as shown in (2), the same note immediately after the rest is added to the original rest position, The melody is modified as shown in FIG. 6B.

The fourth phrase of the melody is shown in FIG. 6C.
, The number of notes is 21
Therefore, the number of syllables of the lyrics “you… で に” (lower in FIG. 6D) corresponding to this phrase needs to be reduced by four to four. Therefore, four notes indicated by * (all of them are notes corresponding to "others") are reduced according to the priority of the matching rule (a). Then, for the third * mark, as shown in (3),
After deleting this note, extend the previous note, and eventually
The melody is modified as shown in FIG. 6D.

Similarly, the melody of the second to fourth and sixth to eighth phrases can be corrected (the description is omitted).

The following is a list of items to be noted with respect to the generation or modification of the lyrics data and the melody data: (1) In the example of FIG. 6, the phrase is changed from the beginning of the first bar to the second bar. However, if there is a pickup (the part into which the previous phrase is embedded), the phrase section is shifted to the left only by this pickup. (2) For syllables, in the explanation so far, syllables (number)
== characters (numbers), but sound-repellent flights (n) and prompting flights (tsu) may be ignored, or "are" may be treated as one syllable. (3) If dissatisfaction occurs when assigning the generated lyrics to the melody, editing may be performed by, for example, generating the lyrics or selecting words again. (4) Although the large number of notes (slight number of notes data) is used as an example of the melody generation data, the number of notes may be specified. In this case, although the number of melody types to be generated is reduced, the number of notes of the lyrics can be specified, so that the assignment to the notes is simplified. (5) In the melody matching process (melody correction process), the priority of the chord sound may be set lower as the deletion target.

[Generation of Accompaniment Data and Output of Performance Data] By the way, the accompaniment generation unit A7
From 1, accompaniment generation data such as style designation data and chord progression data are provided from the music generation data via the music generation data selection unit A3, and the accompaniment data is generated based on the accompaniment generation data. . The accompaniment generation unit A7 is provided as necessary. For example, when singing with a capella, the accompaniment generation unit (A7, B7, C) is used in this embodiment and other embodiments described later.
7) may not be necessary.

Next, the synthesizing unit A8 synthesizes the lyric data generated by the lyrics generation unit A4, the melody data corrected by the melody correction unit A6, and the accompaniment data generated by the accompaniment generation unit A7. Create performance data with lyrics in one file. The output section A9 outputs the performance data.

Examples of the performance data output at the output unit A9 are as follows: (1) Tone generation based on performance data composed of melody data and accompaniment data is performed by a music generation system (8, 9, 15).
Through the display or in the form of a musical score
To be displayed. (2) The lyrics based on the lyrics data are displayed on the display 14 or sung by voice through the tone generation system (8, 9, 15). (3) The data is stored in the storage medium of the external storage device 4 in the format of “performance data + lyrics data” or the format of the audio data described in (2). (4) Attach performance data with lyrics to e-mails and send them to others, or upload them to server computer 20. (5) Play the accompaniment while displaying the lyrics, make the user sing a melody, and record it. And so on.

[Lyson Generation Processing, Melody Generation Processing 1 and Melody Correction Processing Flow] FIGS. 7 to 9 show the lyrics generation unit and the melody of the lyrics composition processing executed in the lyrics composition system according to one embodiment of the present invention. It is a flowchart showing an example of the verb generation process, the melody generation process 1, and the melody correction process respectively performed by the generation unit (1) and the melody correction unit.

First, in the lyrics generation processing of FIG.
In step L1, the lyrics generation unit A4 acquires genre data, music composition data, and rhythm characteristic data from the music generation database A1 via the music generation data selection unit A3. In the next step L2, the number of syllables of the current phrase is determined based on the acquired music composition data and rhythm characteristic data. In the following step L3, the syllable number represented by the genre data and the number of syllables determined in step L2 are determined. Vocabulary / sentence database, and extracts vocabulary / sentence candidates.

Next, in step L4, the vocabulary / sentence candidate extracted in step L3 is presented to the user on the display 14 to prompt the user to select a vocabulary / sentence. Then, in step L5, the selection from the user is received. To determine the vocabulary / sentence, and generate lyrics data of the phrase.

In the next step L6, it is checked whether or not the current phrase is the last phrase. If the current phrase is not the last phrase, the process returns to step L2, and the processes in steps L2 to L6 are repeated for the next phrase. Then, if it is determined in step L6 that the phrase is the last phrase, the flow of the word generation processing ends.

In the melody generation processing 1 of FIG. 8, in the first step M1, the melody generation unit (1) A5
Acquires rhythm feature data, pitch feature data, chord progression data, and song configuration data from the song generation database A1 via the song generation data selection unit A3. In the next step M2, the number of notes of the current phrase is determined based on the acquired rhythm feature data, and the following step M3
Then, a rhythm pattern is determined based on the rhythm characteristic data and the number of notes. Further, in step M4, a pitch is assigned to each hit point of the rhythm pattern based on the pitch characteristic data and chord progression data, and the melody data of the phrase is converted. Generate.

In the next step M5, it is determined whether or not the current phrase is the last phrase. If not, the process returns to step M2, and the processes in steps M2 to M5 are repeated for the next phrase. Then, step M5
If it is determined that the melody is the last phrase, the melody generation processing 1 is terminated.

Returning to step M2, when melody generation is repeated for a new phrase, a melody is newly generated for a phrase which is the same as the preceding phrase in the phrase configuration, as in steps M2 to M5. It is better to copy the melody of the previous passage without doing it. In addition, for a similar phrase in the phrase configuration, it is preferable to copy a part of the melody of the preceding phrase.

In the melody correction process of FIG. 9, when the melody correction unit A6 acquires the melody data generated by the melody generation unit (1) A5 and the lyrics data generated by the lyric generation unit A4, the first step N1 Then, it is checked whether or not the number of notes in the melody data in the current phrase is larger than the number of syllables in the lyrics data.

[2] Lyrics Composition Process of Second Embodiment FIG. 10 is a functional block diagram of a lyric composition process of the second embodiment which is executed by the lyric composition system according to one embodiment of the present invention. In the songwriting process of the second embodiment,
The melody data is generated according to the number of syllables in the lyrics data. In other words, the melody generation unit (2) B5 is provided instead of the melody generation unit (1) A5 of the first embodiment, the melody correction unit A6 of the first embodiment is eliminated, and another database and processing unit B1 ~ B4, B7
As shown, B9 to B9 have substantially the same configuration as the database and processing units A1 to A4 and A7 to A9 of the first embodiment, respectively.

When determining the number of notes in the melody data, the melody generating unit (2) B5 in the songwriting process according to the second embodiment sets the number of syllables equal to the number of syllables of the lyrics data generated by the lyric generating unit B4. . That is, the melody generation unit (2)
In B5, melody generation processing 2 described below is executed,
The number of notes is determined from the number of syllables in the lyrics data without using data on the number of notes in the melody generation data. Therefore, the number of syllables of the (song) lyrics and the number of notes of the melody can be matched with a simple configuration without providing the melody correction unit A6 as in the first embodiment.

[Melody Generation Process 2] FIG. 11 shows an example of the melody generation process 2 executed by the melody generation unit (2) in the songwriting process performed in the songwriting system according to one embodiment of the present invention. FIG. In the first step P1 of this processing flow, the melody generation unit (2) B5 sends the rhythm feature data, pitch feature data, chord progression data, and song configuration data from the song generation database B1 via the song generation data selection unit B3. The data is obtained, and the lyrics data generated by the lyrics generation unit B4 is obtained.

In the next step P2, the number of notes of the current phrase is determined in accordance with the number of syllables of the (song) phrase represented by the lyrics data. In the next step P3, the rhythm pattern is determined based on the rhythm characteristic data and the number of lyric notes. Then, in step P4, based on the pitch feature data and the chord progression, a pitch is given to each hit point of the rhythm pattern to generate melody data of the phrase.

In the next step P5, it is checked whether or not the current phrase is the last phrase. If not, the process returns to step P2, and the processes in steps P2 to P5 are repeated for the next phrase. Then, step P5
If it is determined that the melody is the last phrase, the melody generation process 2 ends.

When returning to step P2 and repeating the melody generation of the new phrase, in the melody generation process 2, as for the passage which is the same as the previous passage in the passage configuration, the processing in steps M2 to M5 is performed. It is better to copy the melody of the previous passage without generating a new melody. In addition, for a similar phrase in the phrase configuration, it is preferable to copy a part of the melody of the preceding phrase. However, since it is necessary to match the number of notes with the number of syllables of the lyrics, it is preferable to increase or decrease the number of hit points.

[3] Lyrics Composition Process of Third Embodiment FIG. 12 is a functional block diagram of a lyric composition process of the third embodiment executed by the lyric composition system according to one embodiment of the present invention. In the songwriting process of the third embodiment,

That is, a lyric correction unit C6 is provided in place of the melody correction unit (1) A6 of the first embodiment, and the other database and processing units C1 to C5, C
7 to C9 have substantially the same configuration as the database and the processing units A1 to A5 and A7 to A9 of the first embodiment, respectively, as illustrated.

The lyric composer C6 in the lyric composer of the third embodiment executes a lyric amendment process, which will be described later, and calculates the number of syllable syllables of the lyrics data generated by the lyric generator C4 to the melody generator (1). ) Increase or decrease according to the number of notes in the melody data generated in C5. To increase or decrease the number of notes, the modified meaning data (the rightmost column in FIG. 3) attached to each vocabulary / sentence data in the vocabulary / sentence database C2 is used to determine the substantial meaning of the already generated vocabulary or sentence. The number of syllables can be changed without changing. For example, in the case where the seven-syllable word “leaf shakes” in the lyric data is corrected to six syllables in accordance with the number of notes 6 in the melody data, the modification of “the leaf shakes” Leaf shaking ”(6
Syllable). This allows the number of syllables of the lyrics to match the number of notes of the melody without correcting the melody.

[Lyric Correction Processing] FIG. 13 is a flow chart showing an example of the lyrics correction processing executed by the lyric correction section in the lyric composition processing executed in the lyric composition system according to one embodiment of the present invention. Upon acquiring the melody data generated by the melody generation unit (1) A5 and the lyrics data generated by the lyrics generation unit A4, the lyrics correction unit C6 determines the lyrics data of the current phrase in the first step Q1 of this processing flow. Check whether the number of syllables is greater than the number of notes in the melody data.

If the number of syllables in the current phrase is larger than the number of melody notes, the process proceeds to step Q2 to reduce the number of syllables before proceeding to step Q3, otherwise to step Q3. In step Q2, referring to the vocabulary / sentence database, according to the modified example data corresponding to the lyrics data, a modified example of the number of syllables corresponding to the number of melody notes is selected as a new (song) word, and the desired number of lyric syllables is determined. To reduce.

At step Q3, it is checked whether or not the number of syllables in the lyrics data in the current phrase is smaller than the number of notes in the melody data. If the number of syllables in the current phrase is smaller than the number of melody notes, the number of syllables in the current phrase is determined in step Q4. , And then proceeds to step Q5, otherwise proceeds directly to step Q5. In step Q5, referring to the vocabulary / sentence database, according to the modified example data corresponding to the lyrics data, a modified example of the number of syllables corresponding to the number of melody notes is selected as a new (song) word, and the desired number of lyric syllables is determined. To increase.

At step Q5, it is determined whether or not the current phrase is the last phrase.
Returning to step Q1, step Q is performed for the next phrase.
The processing of 1 to Q5 is repeated. Then, when it is determined in step Q5 that the phrase is the final phrase, the word correction processing ends.
