Steve Reich: Drumming (complete)

Drumming lasts from 55 to 75 minutes (depending on the number of repeats played) and is divided into four parts that are performed without pause. The first part is for four pairs of tuned bongo drums, stand-mounted and played with sticks; the second, for three marimbas played by nine players together with two women’s voices; the third, for three glockenspiels played by four players together with whistling and piccolo; and the fourth section is for all these instruments and voices combined.

In the context of my own music, “Drumming” is the final expansion and refinement of the phasing process, as well as the first use of four new techniques: (1) the process of gradually substituting beats for rests (or rests for beats); (2) the gradual changing of timbre while rhythm and pitch remain constant; (3) the simultaneous combination of instruments of different timbre; and (4) the use of the human voice to become part of the musical ensemble by imitating the exact sound of the instruments.   —Steve Reich

Drumming begins with two drummers building up the basic rhythmic pattern of the entire piece from a single drum beat, played in a cycle of 12 beats with rests on all the other beats. Gradually additional drumbeats are substituted for the rests, one at a time, until the pattern is completed. The reduction process is simply the reverse where rests are gradually substituted for the beats, one at a time, until only a single beat remains.
