This was created during the period of Covad 19, and is given the “#19” in the title in dubious honor of our sheltering in place; all the extra time allowed me to keep playing with the possibilities the Finale notation and playback programs offer. If I did not post the piece today (May16) it might continue to expand and morph indefinitely, just like the virus!
The piece presents contrapuntal development of a musical line that fascinated me; much like the virus, it morphs into something quite different from the original line. If it gets too loud, do not worry, it will soon become different. For fibonacci folk, the duration of sections turned out to be 13-21-8-13-13 (not pre-planned).
