Searching for Coincidences is a duet for flutes, inspired largely by the indeterminate works of Earle Brown and Christian Wolff. Each player is presented with five staves, from which they can create their own custom "path" through the work. The pitch material is based mainly on diatonic harmonies and scales, but these harmonies and scales may become more pronounced or more obscured, depending on the paths chosen by the two players.

I was very interested in indeterminate music around the time I wrote this, as also reflected by pieces like Six Textures for Rock Quartet, Pachamama, and Figures in Bas-Relief. Although I sometimes use chance processes to determine pitches and rhythms, what still fascinates me more is when performers have more input into the outcome of the piece.
So here, the form is more or less determined, but each player can choose among 5 options at any given time. When you look at the score, you'll see that every gesture is a recognizable arpeggio or scale. Depending on their choices, this may sound like a lot of atonal gestures, or may coincide on the same tonality for an instant.
