heterogeneous — Claudia Birkholz, performed live in Bremen, Germany
Program Notes
Heterogeneous is a moto perpetuo. I wrote it after a prolonged exposure to the Bach solo cello suites and they serve as my inspiration here. There are compound melodies and few dynamic or articulation indications. I leave the phrasing and other interpretation decisions to the performer — though the electronics force the issue somewhat, encouraging certain performance practices, and discouraging others through sonic encouragement.
