Originally for 4-handed piano, Ma Mère l’Oye was orchestrated by Ravel in 1911, and in the same year it was expanded to a ballet. This version for ensemble is presented in 5 movements and has been orchestrated with both the orchestral and the piano versions, so it is possible to make small changes to some sections while safeguarding the initial compositional idea, as in the case of the part of the solo contrabassoon from Les entretiens de la belle et de la bête in this version, which is split between doublebass and cello, an idea already suggested in the version orchestrated by Ravel.
