Program Notes: As someone who deals mainly in process-based music, I’ve long considered my music to be largely unemotional, unprogrammatic, or simply music for music’s sake. However, it was through writing Coalescence, a process-based piece just like any other piece of mine, that I’ve truly started to discover the subconscious effects that emotion has on almost every aspect of our lives. One can ascertain the geopolitical climate under which this piece was composed, but aside from that, Coalescence was written in a period of deep personal loss; whether I wanted it to or not, that fact has affected the core of the piece on levels I am only beginning to understand.
Coalescence is my first true experiment with ‘serializing’ rhythm to harmony. I’ve always been fascinated by the fact that polyrhythm and harmony are the same thing on different scales (a 4:5:6 polyrhythm played on an unpitched instrument would sound like a major chord when sped up to an extreme degree), and have always wanted to explore that concept through composition. While Coalescence does not serialize the polyrhythms to the harmonies in the literal sense, it does so in a more subjective and hopefully more organic sense.
Coalescence was commissioned by Robert van Sice and the Yale Percussion Group (YPG) in 2020. I give my unending gratitude to Bob for asking me to write this piece and to Russell Fisher, Jacob Gutierrez, Sijia Huang, Makana Medeiros, Yukiko Nakamura, and Michael Yeung for premiering it. Coalescence is dedicated to my grandparents, Beto and Irma Zetina.
