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.
VIII. Vivace. Energico
The silence of the previous movement is broken by a loud dissonance on octave D's and E's. Thus introduced, the main theme is heard in octaves, a lively and vigorous dance in 7/8. This main theme is characterized by a scalar lower melody in which each note is accompanied by an upper E. After a number of transformations of this melody in the left hand, that hand plays the theme as an accompaniment figure while the right hand plays a light, playful, rhythmically mutated version of the scalar melody from the main theme. This complete, the main theme returns in both hands in all its glory, fading briefly to a restatement of the secondary melody idea before the main theme decisively concludes the movement
Although the rhythmic accent pattern drives the movement, Ligeti deletes beats from certain measures in order to "restart" the pattern in sections in which the left hand restatement of the theme is offset from the right. Ligeti further reinforces the folk-dance origins of the movement by using a great deal of open fifths in the accompaniment that correspond to the open strings on a fiddle or cello. In fact, the many metric "skips" and rhythmic offsets may be referring to folk musicians who accidentally enter at the wrong times.
