"Part II ... consists of 12 short pieces in which musicians create interference patterns between their sounds and those of pure waves ... generated by audio oscillators tuned to specific pitches ... numbers 5 through 8 [are for] one percussionist playing four different mallet instruments"--Notes.
"Since the spatial phenomena in these pieces happen acoustically, in the room in which they sound, listening through headphones is not advised"--Notes.
