Systems, devices, and methods for decoupling note variation and harmonization in computer-generated variations of music data objects

A system for generating a variation of a music data object, the system comprising:

• at least one processor;
• and
• a non-transitory processor-readable storage medium communicatively coupled to the at least one processor, the non-transitory processor-readable storage medium storing the music data object and processor-executable instructions and/or data that, when executed by the at least one processor, cause the at least one processor to:
• characterize a first set of notes in the music data object;
• and
• apply a transformation to the first set of notes in the music data object, wherein the transformation maps at least one note in the first set of notes to at least one note in a second set of notes, and wherein the processor-executable instructions and/or data that, when executed by the at least one processor, cause the at least one processor to apply a transformation to the first set of notes in the music data object, cause the at least one processor to replace, in the music data object, at least one note in the first set of notes with at least one note in the second set of notes in accordance with the transformation that maps at least one note in the first set of notes to at least one note in a second set of notes.

A computer program product for generating a variation of a music data object, the computer program product comprising:

• processor-executable instructions and/or data that, when the computer program product is stored in a non-transitory processor-readable storage medium and executed by at least one processor communicatively coupled to the non-transitory processor-readable storage medium, cause the at least one processor to:
• characterize a first set of notes in the music data object;
• and
• apply a transformation to the first set of notes in the music data object, wherein the transformation maps at least one note in the first set of notes to at least one note in a second set of notes, and wherein the processor-executable instructions and/or data that, when executed by the at least one processor, cause the at least one processor to apply a transformation to the first set of notes in the music data object, cause the at least one processor to replace, in the music data object, at least one note in the first set of notes with at least one note in the second set of notes in accordance with the transformation that maps at least one note in the first set of notes to at least one note in a second set of notes.
