Hindemith wrote much varied music for the piano with orchestral accompaniment. He intended his Theme with Four Variations (The Four Temperaments) as an experimental ballet, and it was first performed in this way in 1946 with choreography by George Balanchine. The manuscript of the Piano Music with Orchestra was found amongst pianist Paul Wittgenstein's papers after his wife's death in 2001. The Concerto for Piano and Orchestra is astutely conceived, whilst the Concert Music for Piano, Brass and Two Harps reveals Hindemith's constant search for varied sound color in his instrumentation.
