Assez animé ("Quite lively"). Dotted half note = 80. A three-part form: A (measures 1-16), B (measures 17-30), A' (measures 31-46).

In contrast to the clear indication of G major at the end of the previous piece, this waltz begins with an elusive sound, whose key is not clearly defined. This is largely because many sections are written using the octatonic scale, or (later) Messiaen's "Mode of Limited Transposition No. 2." By consciously performing the sections that deviate from the traditional tonal system alongside those that are clearly tonal, one can create a grand flow.
