  "provenance": "Independently authored, transposable rhythmic gestures and chord-member traversal operators. No notes, rhythms, measurements, or fitted parameters were extracted from the optional reference scores. Joint gesture operators were motivated by analysis of the supplied validation solos, then authored as general harmonic/rhythmic transformations. No target phrase, position, pitch sequence or frequency is stored.",
