“aaaaccccffffgggg,” is pronounced however you think it is, and is for any number of quartets, playing any type of instrument. Each performer gets to perform 25 notes of little importance and impact on a given set of pitches over the course of a minute. However, the quartet gets to decide who will play an extra note during the piece. This can be done by picking straws, playing rock-paper-scissors, or throwing a dice roll. Whoever wins in that decision-making system gets to play one more note than everyone else, and of significant importance.
