Schumann - "Kleiner Morgenwanderer"

I would have to say that the parallel, symmetrical period found in measures 1-8 is the expository section. Then, beginning at measure 9 is the developmental section. This section lasts until measure 19. From measure 20/21 to the end is the terminative function. There is not much movement out of the A major chord. I like the piece and I find it very bouncey and fun.
