The static sounds of popular music, especially rock <ap>‘n’ roll, influenced a new generation of composers. Rejecting both classical and contemporary formal procedures in composition, minimalist composers created new works whose structures became apparent to the listener as the music slowly unfolded. Beginning with La Monte Young, the master of the drone, a few composers began to simplify their art in an effort to connect to the listening public. The percussion music presented herein exhibits many of the traits that define minimalism: the constant repetitive pulse, reduced forces, slowly changing rhythmic modules, and canonic constructs. A brief look at Terry Riley’s iconic work, In C, leads to an in-depth examination of composer Steve Reich’s most popular minimalist work, Drumming. In it, the listener can hear the slowly unfolding structure of the work as well as the psychoacoustic phenomena caused by the interaction of rhythmic and tonal patterns. The chapter concludes with an examination of works by the Danish composer and theorist Per Nørgård and the American composer James Tenney.
