Percussion ensemble
A percussion ensemble is a musical ensemble consisting of only percussion instruments. Although the term can be used to describe any such group, it commonly refers to groups of classically trained percussionists performing primarily classical music. In America, percussion ensembles are most commonly found at conservatories, though some professional groups, such as Nexus and So Percussion exist. Drumlines and groups who regularly meet for drum circles are two other forms of the percussion ensemble.
Early literature
George Antheil's Ballet Mécanique (1923) is one of the earliest examples of composition for percussion, written originally as a film score and exemplifying the ideals of the Italian futurist movement. Antheil originally called for sixteen synchronized player pianos, as well as airplane engines, alongside more traditional percussion instruments. Another early example, Cuban composer Amadeo Roldán's Ritmicas nos. 5 and 6 of 1930, made use of Cuban percussion instruments and rhythms. But it was Edgard Varèse's Ionisation that "opened the floodgates" and truly brought the percussion ensemble into the fold of contemporary composition. Premiered in 1933 under the baton of Nicholas Slonimsky, Ionisation is thematically structured and makes use of 13 performers playing over 30 different instruments, including Latin percussion instruments, drums, cymbals, sirens, a piano, chimes and glockenspiel.
