Musica ricercata is a set of eleven pieces for piano by György Ligeti. The work was composed from 1951 to 1953, shortly after the composer began lecturing at the Budapest Academy of Music. The work premiered on November 18, 1969 in Sundsvall, Sweden. Although the ricercata (or ricercar) is an established contrapuntal style (and the final movement of the work is in that form), Ligeti's title should probably be interpreted literally as "researched music" or "sought music". This work captures the essence of Ligeti's search to construct his own compositional style ex nihilo, and as such presages many of the more radical directions Ligeti would take in the future.
In response to a request by the Jeney Quintet, six of the movements were arranged for wind quintet as Six Bagatelles for Wind Quintet (1953). They are, in order: III, V, VII, VIII, IX, X.
Eight movements (I, III, IV, VII, VIII, IX, X, XI) were transcribed for bayan by Parisian accordionist Max Bonnay.
