Foray was directly influenced by Augustus Arnone's pianism, which I finally heard in the spring of 2016 in a Collide-O-Scope concert featuring the music of Milton Babbitt and some younger composers. His remarkable ways of voicing and articulating piano sound made a big impression on me. So in mid-July of 2016 an idea for a piano piece popped into my head and the character of the piano ideas was something I thought Augustus would like to play, so I dedicated the piece to him. The basic idea of the piece is that an opening series of ten chords arranged in an arc (maybe a rainbow, since each chord is of a different harmonic “color”) each generate music in subsequent sections of the piece. Thus the form is the arc followed by ten sections in different registers and densities. As the music goes on, the derivation of the music from the chords gets progressively more complicated and obscure in the way the music is parsed, registered, and embellished. The process is from isolated objects to mixtures and blends—an entropic process.
