The heart of this piece is based on the following observation: if one player divides the measure into 7 pulses and accents every five notes, while the other player divides the same measure into 10 pulses and accents every seven notes, the accented notes will slowly phase in a 49:50 ratio.  Since 5 + 7 = 12, one player gets a pentatonic scale while the other gets a diatonic scale, and the pitches then get passed back and forth as the piece progresses.
