The plot thickens. Its marked robust, moderate with a 3/4 time signature and no key signature at all. Thats not because its in C Major, but because a key signature would just get in the way of what Messiaen is trying to do.

There is an eerie beauty to the central section where the clarinet is silent and the piano plays quiet block chords.
