Hyperprism

Hyperprism is a work for wind, brass, and percussion instruments by Edgard Varèse, composed in 1922 and revised in 1923.

The work was first performed at an International Composers Guild concert in the Klaw Theatre on March 4, 1923. The audience laughed throughout the performance and hissed during the ovation. Someone, perhaps Carlos Salzedo, got on the stage and urged the audience to take the work seriously. It was repeated to no better effect on the crowd. There was one report of a fistfight between two men who were exiting the hall.

The piece is scored for flute (doubling piccolo), clarinet in E♭, 3 horns, 2 trumpets in C, tenor and bass trombones, and percussion. The percussion parts call for snare drum, Indian drum, bass drum, tambourine, crash cymbal, 2 cymbals, tam-tam, triangle, anvil, slapstick, 2 Chinese blocks (high and low), lion's roar, rattle, big rattle, sleigh bells, and siren.
