Sonatas & Interludes for Prepared Piano

Sonatas and Interludes for Prepared Piano is a set of solo prepared piano pieces by American composer John Cage, composed between 1946 and 1948. The work employs objects placed among the piano strings to alter timbre and texture, exploring novel sonic colours and formal permutations, and marks an important stage in Cage's early development of prepared-piano techniques that informed later experimental and avant-garde repertoire.
