1937 musical piece written by Béla Bartók

The Sonata for Two Pianos and Percussion, Sz. 110, BB 115, is a musical piece written by Hungarian composer Béla Bartók in 1937. The sonata was premiered by Bartók and his second wife, Ditta Pásztory Bartók, with the percussionists Fritz Schiesser and Philipp Rühlig at the International Society for Contemporary Music (ISCM) anniversary concert of 16 January 1938 in Basel, Switzerland, where it received enthusiastic reviews. Bartók and his wife also played the piano parts for the American premiere which took place in New York City's Town Hall in 1940, with the percussionists Saul Goodman and Henry Deneke. It has since become one of Bartók's most performed works. The score requires four performers: two pianists and two percussionists, who play seven instruments between them: timpani, bass drum (gran cassa), cymbals, triangle, snare drum (both on and off snares), tam tam (gong) and xylophone. In the published score the composer provides highly detailed instructions for the percussionists, stipulating, for example, which part of a suspended cymbal is to be struck with what type of stick. He also provides precise instructions for the platform layout of the four players and their instruments.

The first movement is in a modified version of traditional sonata form. There are clearly delineated sections – introduction, exposition, development, recapitulation and coda – but Bartók eschews the customary relationships between keys, beginning the movement in F and ending in C major, with excursions into several unexpected keys in between. This structural tritone relationship is not unusual for Bartók; it may be found in many of his other compositions, including the first movement of his well known work, Music for Strings, Percussion and Celesta. The rhythm of this movement is varied within an overall time. The movement is also untypical of classical sonata form in that it constitutes half the playing time of the whole work. The world premiere was given at the Royal Albert Hall, London, at a Royal Philharmonic Society concert on 14 November 1942, with percussionists Ernest Gillegin and Frederick Bradshaw, the then husband and wife piano team of Louis Kentner and Ilona Kabos, and the London Philharmonic Orchestra, conducted by Sir Adrian Boult. The composer and Ditta Pásztory Bartók were piano soloists in a performance at Carnegie Hall in New York on January 21, 1943, with the New York Philharmonic conducted by Fritz Reiner. This was Bartók's final public appearance as a performer.
