Heptagram, for solo percussion on seven drums (2019) – 5'

Heptagram is, unsurprisingly given the title, based around sevens. It is played on seven drums, introduced at expanding time intervals, such that the introduction of each of the last two drums marks the beginning of a main section. Once all seven are in play, various cycles going through all seven drums — analogous to different sorts of heptagrams — are interspersed with the existing motives.
