ABSTRACT:
This invention relates to a system and method for altering the harmonic referent of segments of a music composition while maintaining conformity to a harmonic rule-base. It enables one to make changes to the harmonic referent (i.e. chord progression) underlying a segment of music, which causes a change in the pitches within that segment so that the pitches are have a compatible analysis within the new chord progression. The invention can advantageously preserves the harmonic function of each pitch in the segment, while changing the harmonic content of the passage. Further, the invention can preserve the shape of a melody line during such a transformation.
