Drumming (Reich)
Drumming is a piece by minimalist composer Steve Reich, dating from 1970–1971.[1] Reich began composition of the work after a short visit to Ghana and observing music and musical ensembles there, especially under the Anlo Ewe master drummer Gideon Alorwoyie. His visit was cut short after contracting malaria. Classical music critic K. Robert Schwarz describes the work as "minimalism's first masterpiece".[2] Compositional stylePhasingThe piece employs Reich's trademark technique of phasing. Phasing is achieved when two players, or one player and a recording, are playing a single repeated pattern in unison, usually on the same kind of instrument. One player changes tempo slightly, while the other remains constant, and eventually the two players are one or several beats out of sync with each other. They may either stay there, or phase further, depending on the piece. Other techniquesK. Robert Schwarz characterized Drumming as a "transitional" piece between Reich's early, more austere compositions and his later works that use less strict forms and structure. Schwarz has also noted that Reich made use of three new techniques, for him, in this work:[3]
Instrumentation and formIn total, the work requires 9 percussionists. With the additional players, the piece can be performed by 12 or 13 players. The work falls into four parts, with the following instrumentation used in each:[3]
The length of the piece can vary widely, as the number of repeats taken on any given measure is up to the performers. Recordings of the piece span between 55 and 84 minutes. The entire piece is structured around a single repeated rhythm, one measure of 12/8 long. This rhythm is built up note by note, in the "substitution of beats for rests" technique found in other of Reich's works such as Music for Pieces of Wood, Octet, Music for 18 Musicians, and others. After the rhythm is completely built up, two of the players phase to where they are playing the same pattern one quarter-note apart from each other, and the other bongo players play resulting patterns that can be heard as a result of the combination of the phased patterns. The rest of the piece continues to use the techniques of beat/rest substitution, phasing, and resultant patterns through its four movements. The transitions consist as follows:
Variations in movement 4In the end of movement 4, in parts 7–9 there is a variation of the rhythmic pattern that Reich uses throughout the piece. Instead of repeating exactly the same motives at a different rhythmic interval, Reich leaves a note out of each final pattern in those parts. Adam Sliwinski, a member of the percussion quarter Sō Percussion, noticed this. Sō Percussion had been performing and teaching Drumming. At first Sliwinski thought it might have been accidental and decided to email Reich to see whether the composer had made a mistake. Reich replied that it was not a mistake, but that it sounds better that way, as the entire pattern would make it sound too heavy. Sliwinski notes that he was surprised by this response, as he had known Reich to strictly adhere to the processes he used in his compositions.[4] While this is true for his earlier work, Reich would diverge from strict processes more in later works. CollaborationsChoreographers such as Laura Dean, Anne Teresa De Keersmaeker, and Ginette Laurin have collaborated on dance performances with Reich on Drumming.[5][6] Recordings
