Automatic composer

1. A method comprising:

receiving, by a processor, music performance data;

segmenting, by the processor, the music performance data based on at least one structural attribute into at least a first musical segment, wherein the first musical segment is associated with at least one musical attribute, and wherein the first musical segment has at least one of a corresponding prologue, epilogue, and verse;

determining, by the processor, an affinity value for the first musical segment based on the at least one musical attribute, wherein the affinity value represents a degree of similarity between the first musical segment and a second musical segment having the at least one musical attribute; and

generating, by the processor, a musical composition based on the affinity values associated with the first musical segment and the second musical segment.

2. The method of claim 1 , wherein the receiving is performed by an automatic composer engine implemented by the processor, the segmenting is performed by a segment creator engine implemented by the processor, the determining is performed by an affinity calculating engine implemented by the processor, and the generating is performed by a composer engine implemented by the processor.

3. The method of claim 1 , wherein the second musical segment is segmented from another music performance data different than the music performance data.

4. The method of claim 1 , wherein the at least one musical attribute is included in segment creation rules and includes melody, harmony, and rhythm.

5. The method of claim 1 , wherein generating the musical composition includes incorporating a transition segment between two successive musical segments.

6. The method of claim 1 , wherein affinity rules are user selectable.

7. The method of claim 6 , wherein the affinity rules correspond to at least one musical attribute selected from the group consisting of tempo, chord, and tone.

8. The method of claim 1 , wherein the affinity value is determined by adding affinity subvalues for two or more different musical attributes.

9. The method of claim 1 , wherein generating the musical composition is performed by matching two segments having a predetermined affinity value.

10. The method of claim 1 , wherein music data corresponding to the prologue and the epilogue include tones that are devoid of melody, harmony, and rhythm.

11. The method of claim 1 , wherein the at least one structural attribute includes a number of musical bars.

12. A non-transitory computer-readable medium having a computer-readable program code configured to cause a processor to perform operations comprising:

receiving music performance data and analysis data;

segmenting the music performance data based on at least one structural attribute into at least a first musical segment, wherein the first musical segment is associated with at least one musical attribute, and wherein the first musical segment has at least one of a corresponding prologue, epilogue, and verse;

determining an affinity value for the first musical segment based on the at least one musical attribute, wherein the affinity value represents a degree of similarity between the first musical segment and a second musical segment having the at least one musical attribute; and

generating a musical composition based on the affinity values associated with the first musical segment and the second musical segment.

13. The computer-readable medium of claim 12 , wherein the at least one musical attribute is included in segment creation rules and includes melody, harmony, and rhythm.

14. A system comprising:

a user interface;

one or more data processors coupled to the user interface; and

one or more non-transitory computer-readable storage media containing instructions configured to cause the one or more data processors to perform operations comprising:

receiving music performance data and analysis data;

segmenting the music performance data based on at least one structural attribute into at least a first musical segment, wherein the first musical segment is associated with at least one musical attribute, and wherein the first musical segment has at least one of a corresponding prologue, epilogue, and verse;

determining an affinity value for the first musical segment based on the at least one musical attribute, wherein the affinity value represents a degree of similarity between the first musical segment and a second musical segment having the at least one musical attribute;

generating a musical composition based on the affinity values associated with the first musical segment and the second musical segment; and

presenting the musical composition to the user interface.

15. The system of claim 14 , wherein presenting the musical composition comprises arranging the first musical segment and the second musical segment vertically offset from one another.

16. The system of claim 14 , wherein presenting the musical composition comprises arranging the first musical segment and the second musical segment directly adjacent to one another.

17. The system of claim 14 , wherein in the second musical segment is segmented from another music performance data different than the music performance data.

18. The system of claim 14 , wherein the at least one musical attribute is included in segment creation rules and includes melody, harmony, and rhythm.

19. A method comprising:

receiving, by a processor, music performance data;

segmenting, by the processor, the music performance data based on at least one structural attribute into at least a first musical segment,

wherein the first musical segment is associated with at least one musical attribute including one of a melody, harmony, rhythm, tempo, or tone, and

wherein the first musical segment a prologue, epilogue, or verse;

determining, by the processor, an affinity value for the first musical segment based on the at least one musical attribute,

wherein the affinity value represents a degree of similarity between the first musical segment and a second musical segment having the at least one musical attribute; and

generating, by the processor, a musical composition based on the affinity values associated with the first musical segment and the second musical segment.
