This movement is for piano and cello, is marked infinitely slow, ecstatic, and is in a straightforward E Major. But there is no time signature. The bars are uneven, and Messiaen uses a basic pulse of sixteenth note = 44 to hold it together. The piano plays in the bass clef throughout.
Im neither emotional nor religious, but this movement always has me going for my handkerchief.
