György Ligeti (1923–2006) was a Hungarian composer of contemporary classical music. He has been described as "one of the most important avant-garde composers in the latter half of the twentieth century" and "one of the most innovative and influential among progressive figures of his time".
Musica ricercata is a set of eleven pieces for piano by György Ligeti. The work was composed from 1951 to 1953.
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.
VI. Allegro molto capriccioso
Yet another abrupt change in mood brings us to the sixth movement, itself characterized by rapid and unexpected changes of dynamics, register, articulation, and musical material. A descent from E to A (thus tentatively establishing an A-major tonality) defines the initial melodic material while a scalewise ascent from A to E is heard in the left hand accompaniment. Eventually the upward and downward motives mix and recombine, jostled together in a melodic toy-box. The piece ends on an appropriately awkward and unexpected E (from an F♯-minor/B-minor polychord), leaving the listener with a lack of resolution.
