Various basic parameters are determined, and a basic key determination section 51, a transposition determination section 52, a bass line determination section 53, a chord determination section 54, a tension determination section 55, and a melody determination section 56 are provided.

The basic tone determining section 51 determines the first column, first row (x
= 1 and y = 1), the basic tone of the music generated by the music generation system 1 is determined according to the type of the sequence block S located at the uppermost stage.

The transposition determining unit 52 uses the first column / arbitrary row (x =
When the white or black sequence block S is located at the uppermost stage of (n, y = 1), a predetermined modulation is determined in that row.

The baseline determining unit 53 determines the music generation system 1 according to the type of the sequence block S in the first row (x = 1, 2, ..., Y = 1) and the first stage (z = 1) of each row (x = 1, 2, ..., Y = 1). Is to determine the baseline of the music that occurs. However, if there is only one stage of the sequence block S in all the rows (x = 1, 2, ...) Including the first row (x = 1), the baseline determination unit 53 generates a baseline sound. Instead, the chord determination unit 54 is configured to generate only chord sounds.

The code determining unit 54 uses the first column / each row (x =
The code of the music generated by the music generation system 1 is determined according to the type of the sequence block S in the second stage (z = 2) of 1, 2, ..., Y = 1). However, when the sequence block S of the second stage (z = 2) exists only in the first row (x = 1), all rows (x = 1, 2, ...) Including the first row (x = 1). In (), the baseline determination unit 53 generates a baseline sound, and only the first line (x = 1) generates a chord sound in addition to the baseline sound. If the baseline determined by the type of sequence block S in the first stage (z = 1) is contrary to the code determined by the type of sequence block S in the second stage (z = 2), The code is prioritized and the baseline is corrected and changed so as not to violate the code.

The tension determining section 55 determines whether the music generation system 1 is dependent on the kind of the sequence block S in the third column (z = 3) of the first column / row (x = 1, 2, ..., Y = 1). It is designed to determine the tension of the generated music. However, the tension is supplemented by making necessary corrections and changes in consideration of the baseline and chord progression. Also, when a tension (avoid note) that cannot be included in the original chord function is given, the chord function is reassigned, assuming that the chord has been changed to a close relative.

The melody determining section 56 determines the first column, each row (x
= 1, 2, ..., Y = 1), the melody of the music generated by the music generation system 1 is determined by the type of the uppermost sequence block S of the third stage and above. However, for example, when the sequence block S of the third stage (z = 3) includes only the first line (x = 1) including the second stage (z = 2), the first line (x = 1) The bass line sound and the chord sound are generated in all lines (x = 1, 2, ...) Including, and only the first line (x = 1) generates the melody sound in addition to the bass line and the chord sound. .
Then, the flow of the melody is as follows in the first column, each row (x = 1,
2, ..., y = 1), it is determined by referring to the transition of the top and bottom (block height) before and after, and the note value (note length) in each bar (row) of the melody is also 3 It is determined by the type of the uppermost sequence block S above the eye.

Further, the parameter determination module 50 is
It is provided with an on / off / volume / tempo determination unit 61 for determining the on / off / volume / tempo of music generated by the music generation system 1 regardless of whether the sequence blocks S are connected.

Further, the parameter determination module 50 is
The vertical length of the concatenated sequence blocks S, that is,
In the sequence block S of (y = 1, z = 1), the x coordinate (x · max) of the largest ordinate is determined as the total number of measures n, and the number of measures for repeating the sound of all measures is determined. The unit 62 is provided.

Further, the parameter determination module 50 is
The width of the connected sequence blocks S, that is,
A part determination unit 63 that adds a musical instrument part according to the song style each time the number of connected sequence blocks S of (x = 1, z = 1) increases. That is, y =
In the case of 1, chord instruments (synthesizer, piano, etc.)
If y = 2, a bass instrument (electric bass, tuba, etc.) is added, and if y = 3, a rhythm instrument (drum, percussion, etc.) is added, y
= 4, melody instrument (voice, strings, etc.)
If y = 5 to 16, add a part that can form a valid ensemble for the song style,
When y = 17 or more, it does not change.

Further, the parameter determination module 50
Includes a song style determination unit 64 that captures the 3D array of each sequence block S as a solid and matches the preset shape as meta to determine the song style. Here, the song style is a group of music determinants such as basic rhythm, musical instrument composition, chord composition, and melody. Examples of meta-images include rock and pop in cities (tools, vehicles, etc.), jazz in cities (houses, buildings, etc.), samba, bossa nova in nature (mountains, birds, etc.), and nature (animals, etc.) in nature. Traditional traditions (castles, temples, etc.) such as African are chamber orchestra, classical music, traditions (farms, etc.) are country, folklore, etc.

Therefore, changing the vertical length x rows, horizontal width y columns, and height z steps of various shaped objects formed by variously connecting the sequence blocks S causes a change in the generated music. That is, the maximum length x rows of the modeled object determines the number of measures (repeat) of the music, the maximum width y column of the modeled object determines the musical instrument part, and the maximum of each row of the modeled object. The height of the z stage determines the harmony structure and melody.

Next, the operation of the above embodiment will be described.
This will be described with reference to the connection diagrams shown in FIGS. In each of these, an appropriate number of sequence blocks S, S, ... With reference to the core block C are arranged in a plurality of rows (x
= 1,2,3, ...) and, if necessary, stacked in a plurality of stages (z = 1,2,3, ...) in the height z direction, and only one row in the lateral width y direction. (Y = 1) is shown. Therefore, in the following description, the coordinates (x
= A, y = b, z = c), the width y is all 1 and therefore omitted (x = a, z = c), and further represented as (a, c).

<Specific Example 1> As shown in FIG. 6, in the core block C, the first line red, the second line green, the third line red, the fourth line green,
In order of four sequence blocks SR (1,1), SG
When (2,1), SR (3,1) and SG (4,1) are connected.

In this case, the total number of measures is four measures, and since the sequence block has only one stage, no baseline sound is generated and only all measure chord sounds are generated. The basic tone is determined to be C by SR (1,1), and the chord function is I (red) -V (green) for the basic tone C.
-I (red) -V (green). And the code function is I
In the case of −V, the chord of V is preset to the complementary data storage memory 40 such that it is G7 instead of G, so that the progression of the generated chord sounds is C-G7-C-G.
7, which is repeated an appropriate number of times.

Further, since there is no sequence block of the third stage or higher, no melody is generated.

<Specific Example 2> As shown in FIG. 7, a sequence block SR (1, 2) of the first row and the second row of red is placed on the first row (first row) of the red of the specific example 1 of FIG. When connected.

In this case, the bass sound is generated in all measures, and the chord function is generated only in the first measure. The basic tone is determined to be C by SR (1, 2), and the baseline is I (red) -V (green) -I (red) -with respect to the basic tone C.
It becomes V (green). Further, since the chord function of the first measure is I (red) with respect to the basic tone C, the chord sound of C is generated.

As a result, at the 1st measure, a bass sound having a C chord sound and a C sound as a root sound is generated, and after the 2nd measure, a G sound-C sound-G sound as a base sound. The sound of the line is generated. In the code column of the figure, C-G7-C
-G7 is written, but G7-CG after the second measure
No. 7 only shows a chord based on the baseline, and does not mean that the chord sound is generated.

Further, since there is no sequence block of the third stage or higher, no melody is generated.

<Specific Example 3> As shown in FIG. 8, the sequence block SY (1,3) of the first row and the third row yellow is connected on the first row, the second row red of the specific example 2 of FIG. If.

In this case, the basic tone is changed to A by SY (1,3). The tension of the first bar is SY
By (1,3), SR (1,2) immediately below is determined to be 6. The chord function is I (red) for basic tone A-
V (green) -I (red) -V (green), and since the tension of the first measure is 6, the progression of the generated chord sound is A6-E7-A-E7, which is repeated as many times as necessary. It

The baseline is I (red) for the basic tone A
-V (green) -I (red) -V (green), so A sound -E
A sound of the baseline is generated, with each of the sound-A sound-E sound as a root sound.

In the first measure, SY (1,3) produces a large note value (long note length) and the flow descends (3).
→ The melody sound that occurs in 1) is generated.

<Specific Example 4> As shown in FIG. 9, the sequence block SR (1, 4) of the first row and the fourth level red is connected on the first row, the third level yellow of the specific example 3 in FIG. , 2 lines (1
(2nd row) 2nd row blue and 2nd row 3rd row blue sequence block SB (2, 2) (2, 3)
In addition, the sequence block SR (3, 2) of the third row and the second row red is connected on the third row (first row) red, and further the fourth row 2 on the fourth row (first row) green. When the sequence blocks SG (4,2) (4,3) of the green in the fourth row and the green in the fourth row and the third row are connected.

In this case, the basic tone is changed to C by SR (1,4). Concrete example 3 for the tension of the first bar
Similar to (FIG. 8), it is determined to be 6. The tension of the second bar is determined by SB (2,3) to be 8 with respect to the SB (2,2) immediately below, and the tension of the fourth bar is SG.
(4,3) determines 8 for SG (4,2) immediately below. The chord function is I (red) for basic tone C-
IV (blue) -I (red) -V (green), and because the tension of the first measure is 6, the progression of the generated chord sound is C6-FC-G7, which is repeated as many times as necessary. It

The baseline is I (red) for the basic tone C
-V (green) -I (red) -V (green), but since the chord function of the second bar is IV, the baseline is also corrected at the second bar to become I-IV-IV. Therefore, C sound-F
A sound of the baseline is generated, with each of the sound-C sound-G sound as a root sound.

A melody sound is generated at the first, second, and fourth measures. That is, in the first measure, SR (1, 4) causes the flow to fall (4) with an intermediate tone value (medium tone length).
→ 3) The melody sound is generated, and in the second measure, S
Due to B (2,3), a melody sound with a slightly finer note value (slightly shorter note length) and a downward flow (3 → 2) is generated, and in the fourth measure, SG (4,3) is generated. Causes the flow to rise (3 → 4) with an intermediate tone value (medium tone length)
A melody sound is generated. Here, the flow of the melody of the 4th measure rises (3 → 4) from the 4th measure to the 1st measure.
This is because it is repeated in measures.

<Specific Example 5> As shown in FIG. 10, in addition to the specific example 4 of FIG. 9, sequence blocks SR (5, 5) of the first stage red, the second stage red and the third stage red are included in the fifth line. 1) (5
2) Connect (5, 3), and in the 6th line, 1st stage red, 2
The red sequence block SR (6, 1) (6,
The sequence blocks SG (6, 3) (6, 4) of 2), 3rd green and 4th green are connected, and the 1st red and 2nd red sequence blocks are located in the 7th row. SR (7,
1) Connect (7, 2), and in the 8th row, 1st stage green, 2
Green sequence block SG (8,1) (8,2)
And the sequence blocks SP (9,1) (9,2) of the first stage purple, the second stage purple, and the sequence block SG (9,3) of the third stage green are connected in the 9th row. The sequence blocks SG (10, 1) (10, 2) of the first green line, the second green line, and the sequence block SY (10, 3) of the third yellow line are connected in the 10th row. And again
On the 11th row, the sequence blocks SR (11, 1) (11, 2) (11, 1st stage red, 2nd stage red and 3rd stage red)
3), and by further connecting the sequence blocks SG (12,1) (12,2) of the first green and the second green in the 12th row, the sequence blocks for a total of 12 measures are connected. if you did this.

In this case, the chord function after the fifth measure is I (red) -I (red) -I (red) -V with respect to the basic tone C.
(Green) -IIm (purple) -V (green) -I (red) -V (green). The tension of the fifth bar is determined by SR (5,3) to be 8 with respect to the SR (5,2) directly below, and the tension of the sixth bar is S (immediately below) by SG (6,3).
It is determined to be -7 for R (6,2). The tension of the 9th bar is SG (9, 3), and SP (9,
11 for 2) [green for purple (SP) (S
G) is the same as blue (SB) for red (SR) (see FIG. 4)], but in this case, the tension is determined to be -7 by the complement function preset in the complement data storage memory 40. It The tenth bar tension is SY
By (10, 3), for SG (10, 2) immediately below, [yellow (SY) for green (SG) is similar to purple (SP) for red (SR) (see FIG. 4)], 9 is decided. The tension of the 11th bar is SR (11,3)
Then, SR (11, 2) immediately below is determined to be 8. Therefore, the progression of the generated chord sounds is C6-F-C-G7-C-C7-C-G7-Dm in order from the first measure.
7-G9-C-G7, which is repeated an appropriate number of times.

With respect to the basic tone C, the baselines after the fifth measure are almost the same as I (red) -I (red) -I (red) -V.
(Green) -II (purple) -V (green) -I (red) -V (green). Therefore, in order from the first measure, C sound-F sound-C sound-
G sound-C sound-C sound-C sound-G sound-D sound-G sound-C sound-G
A bass line sound is generated with each sound as a root note.

In addition, the flow of the melody of the fourth measure is changed from rising (3 → 4) to parallel (3 → 3), and after the fifth measure, the melody starts at the fifth, sixth, ninth, tenth and eleventh measures. Sound is generated. That is, in the fifth measure, SR (5,3)
Produces a melody sound with an intermediate tone value (medium tone length) and a rising flow (3 → 4), and in the sixth measure SG (6, 4) produces an intermediate tone value ( A melody sound that the flow is descended (4 → 2) is generated with the sound length being medium, and SG (9, 3) is used in the ninth measure, so that the note value is intermediate (the sound length is medium). ), A parallel (3 → 3) melody sound is generated, and SY (1
0,3) produces a melody sound with a large note value (long note length) and a parallel flow (3 → 3). In measure 11 SR (11,3) produces a note value. Is intermediate (sound length is medium) and the flow descends (3 → 2) to generate a melody sound.

<Specific Example 6> As shown in FIG.
Of Example 5, the sequence block SB (4, 4) of the 4th row and the 4th stage and the sequence block SW (4, 5) of the 4th row and the 5th stage of white are connected on the 4th row and the 3rd stage green. ,Also,
8th row 3rd row green sequence block SG (8,3), 8th row 4th row blue sequence block SB (8,4), 8th row 5th row purple sequence on top of 8th row 2nd row green Block S
When P (8, 5) and the sequence block SK (8, 6) of the 8th row and the 6th row black are connected.

In this case, SW (4, 5) of the 4th measure transposes from the basic key C up to the 3rd bar to F (major) of SB (4, 4), and SK of the 8th measure. (8,6)
Depending on, from F up to the 7th bar to D of SP (8,5)
Transpose to (minor).

Therefore, since the chord functions V (green) -I (red) -I (red) -I (red) from the 4th bar to the 7th bar become the chord functions for the transposed F, from the 4th bar. The progression of the chord sounds generated up to the 7th measure is C7-FF
7-F. In addition, a baseline sound having roots of C sound-F sound-F sound-F sound is generated.

Further, the chord function from the eighth measure to the twelfth measure is the V (green) -value up to that time (concrete example 5: FIG. 10).
From IIm (purple) -V (green) -I (red) -V (green) to minor chord function V (green) -IIm-5 (purple) -V (green) -I
Changed to m (red) -V (green). The tension of the 8th bar is 8 with respect to the SG (8, 2) immediately below by SG (8, 3), but in this case, the complementary data storage memory 40
The tension is determined to be -9 by the complementary function set in advance. Example 5 for the tension of the 9th measure
As in (Fig. 10), it is determined to be -7, and the tension of the 10th bar is SG (1) immediately below by SY (10, 3).
It becomes 9 for 0, 2), but in this case, by the complementary function preset in the complementary data storage memory 40,
Tension is determined to be -9. The tension of the 11th bar is determined as 8 as in the specific example 5 (FIG. 10). Therefore, the progression of the chord sound generated from the 8th bar to the 12th bar is A7 ♭ 9-Em7 ♭ 5-A7 ♭ 9-Dm-A7. In addition, a baseline sound having roots A, E, A, D, and A is generated.

Therefore, the progression of the generated chord sound is 1
C6-F-C-C7-F-F7-F-
A7 ♭ 9-Em7 ♭ 5-A7 ♭ 9-Dm-A7,
This is repeated an appropriate number of times.

In addition, from the first measure, C sound-F sound-C
Sound-C sound-F sound-F sound-F sound-A sound-E sound-A sound-D sound-A sound of the base line is generated with each root sound.

Further, the melody of the fourth measure is changed.
That is, in the fourth measure, SB (4, 4) causes the note value to be slightly fine (the note length is slightly short) and the flow to descend (5
→ 3) A melody sound occurs. Also, no melody occurs in the eighth measure.

<Specific Example 7> As shown in FIG.
Of the concrete example 6 above, the sequence block SW (7, 3) of the 7th row and the 3rd row white is connected on the 7th row and the 2nd row red, and the 9th row 3
Sequence block SR of 9th row and 4th row red on top of the green row
(9, 4) and the sequence block SW (9, 5) of the 9th row and the 5th row of white are connected, and the sequence block SG (1 of the 12th row and the 3rd row of green is further provided on the 12th row and the 2nd row of green.
When 2, 3) are connected.

In this case, SW (7,3) of the 7th bar transposes from F up to the 6th bar to C (major) of SR (7,2), and SW (9 of the 9th bar). , 5), transpose from D (minor) of the eighth measure to C (major) of SR (9, 4).

The chord function I (red) of the seventh measure becomes the chord function for the transposed C, and the tension is SW (7,
It becomes alt by 3), but in this case, by the complementary function preset in the complementary data storage memory 40,
Tension is decided at -7. Therefore, the generated chord sound is C7. In addition, a bass sound having the C sound as a root sound is generated.

The chord functions from the ninth measure to the twelfth measure are the minor chord functions up to that time (concrete example 6: FIG. 11).
From IIm-5 (purple) -V (green) -Im (red) -V (green), major chord function IIm (purple) -V (green) -I (red)
-Changed to V (green). The tension of the ninth measure is determined to be -7 as in the concrete example 6 (Fig. 11), the tension of the tenth measure is determined to be 9 as in the concrete example 5 (Fig. 10), and the tension of the eleventh measure. Example 6 (Fig. 1
Similar to 1), it is determined to be 8. The tension of the twelfth bar becomes 8 with respect to the SG (10, 2) immediately below due to SG (12, 3), but in this case, the complementary data storage memory 40
The tension is determined to be -7 by the complementing function set in advance. Therefore, the progression of the chord sound generated from the 9th bar to the 12th bar is Dm7-G9-C-G.
It becomes 7. In addition, a baseline sound having roots D, G, C, and G is generated.

Therefore, the progression of the generated chord sound is 1
C6-F-C-C7-F-F7-C7 in order from the bar
-A7 ♭ 9-Dm7-G9-C-G7, which is repeated an appropriate number of times.

Also, from the first measure, C sound-F sound-C
Sound-C sound-F sound-F sound-C sound-A sound-D sound-G sound-C sound-G sound is generated as a root sound.

Further, the flow of the melody of the sixth measure is changed from the descending (4 → 2) to the descending (4 → 3), and the seventh measure
In the measure, SR (7, 2) immediately below SW (7, 3) causes the flow to rise (3) with an intermediate tone value (medium tone length).
→ 6) Melody sound is generated. Also, the melody flow of the 9th bar is changed from parallel (3 → 3) to descending (5 → 3), and the melody flow of the 11th bar is descending (3).
→ 2) changed to parallel (3 → 3), and
In the measure, due to SG (12, 3), a melody sound having a middle tone value (medium tone length) and a rising flow (3 → 4) is generated. Here, the reason why the melody flow of the twelfth bar rises (3 → 4) is that the melody is repeated from the twelfth bar to the first bar.

In the above embodiment, ten kinds of sequence blocks are selected from red (SR), orange (SO), and yellow (S).
Y), green (SG), blue (SB), indigo (SI), purple (S
P), white (SW), black (SK), transparent (ST) are distinguished by 10 colors, and among these, 7 types (7 colors) of red, orange, yellow, green, blue, indigo, and purple are sequenced.
