The Sonatine (Sonatina) for violin and piano is a chamber music composition by Karlheinz Stockhausen, written while he was still a student in 1951.

It was premiered by Wolfgang Marschner, concertmaster of the NWDR Symphony Orchestra, with the composer at the piano, in a broadcast recording transmitted for the first time on 24 August 1951.

[1][3] The first performance before a live audience, however, did not occur until twenty years later, when Saschko Gawriloff (violin) and Aloys Kontarsky (piano) played it on 22 October 1971 at a concert of the SMIP in Paris.

[1][4] The work is not so much an integrated composition as three disparate style exercises, related only through the use of a common twelve-tone row in which thirds and perfect fifths predominate.

The movement is through-composed with an overall slowing process which Stockhausen described as "incredibly meditative, like Stimmung", and ends with the violin playing sextuplets against quadruplets in the piano.
