Clapping

A clap is the percussive sound made by striking together two flat surfaces, as in the body parts of humans or animals. Humans clap with the palms of their hands, often quickly and repeatedly to express appreciation or approval (see applause), but also in rhythm to match the sounds in music, dance, chants, hand games, and clapping games.

Some people slap the back of one hand into the palm of the other hand to signify urgency or enthusiasm. This act may be considered uncouth by others.

Clapping is used as a percussion element in many forms of music. One example is in gospel music. In flamenco and sevillanas, two Spanish musical genres, clapping is called palmas and often sets the rhythm and is an integral part of the songs. A sampled or synthesized clap is also a staple of electronic and pop music.

Clapping Music

Clapping Music is a minimalist piece written by Steve Reich in 1972. It is written for two performers and is performed entirely by clapping.

A development of the phasing technique from Reich's earlier works such as Piano Phase, it was written when Reich wanted to (in his own words) "create a piece of music that needed no instruments beyond the human body". However, he quickly found that the mechanism of phasing slowly in and out of tempo with each other was inappropriate for the simple clapping involved in producing the actual sounds that made the music.

Instead of phasing, one performer claps a basic rhythm, a variation of the fundamental African bell pattern in 12/8 time, for the entirety of the piece. The other claps the same pattern, but after every 8 or 12 bars shifts by one eighth note to the right. The two performers continue this until the second performer has shifted 12 eighth notes and is hence playing the pattern in unison with the first performer again (as at the beginning), some 144 bars later. The variation of the African bell pattern is minimal; it contains just one additional beat. However, this minimal addition results in a much more interesting piece from the point of view of the variation of syncopation as the piece progresses.

Steve Reich

Stephen Michael Reich (/ˈraɪʃ/; born October 3, 1936) is an American composer who, along with La Monte Young, Terry Riley, and Philip Glass, pioneered minimal music in the mid to late 1960s.

Reich's style of composition influenced many composers and groups. His innovations include using tape loops to create phasing patterns (for example, his early compositions It's Gonna Rain and Come Out), and the use of simple, audible processes to explore musical concepts (for instance, Pendulum Music and Four Organs). These compositions, marked by their use of repetitive figures, slow harmonic rhythm and canons, have significantly influenced contemporary music, especially in the US. Reich's work took on a darker character in the 1980s with the introduction of historical themes as well as themes from his Jewish heritage, notably the Grammy Award-winning Different Trains.

Writing in The Guardian, music critic Andrew Clements suggested that Reich is one of "a handful of living composers who can legitimately claim to have altered the direction of musical history". The American composer and critic Kyle Gann has claimed that Reich "may...be considered, by general acclamation, America's greatest living composer".
