As a foil to Ichiyanagi’s Music for Piano No. 4, in his Music for Piano No. 5, all events must be punctual “attacks.” This timeline-based score uses proportional rhythms; each line represents one minute, and the numbers correspond to precise seconds on a stopwatch. Any number of players can be involved, but strict numbers of attacks must be made at specific times.
