43 is a ballet score by the French composer Albert Roussel written in 1930.
[1] Its composition roughly coincides with that of Roussel's Symphony No.
The Paris Opera premiered the two-act work under the direction of Philippe Gaubert on 22 May 1931, with choreography by Serge Lifar and sets by Giorgio de Chirico.
[2] Roussel created two orchestral suites from the score, the first premiered by Charles Münch on 2 April 1933, and the second by Pierre Monteux a year later.
A late work, the piece reflects Roussel's distinctive orchestration style and his preference for late classical rhythms and harmonies.
