In terms of structure:
Introduction (b.1-8)
A (b.9-24)
B (b.25-40)
C (b.41-64), I combine and develop both melodies from previous materials, while adding a new dance-like melody. Clarinet melody of b.41-42 and b.48-50 are from A, the ascending 5th motion of b.50-51 is from B. Clarinet theme gets repeated on the piano starting from b.53.
B* (b.65-78), with the ostinato and thirds from the intro.
Cadenza (b.79-100), contains materials from A and B.
A* (b.101-120), I develop the theme a bit more with a climax at the end.
B** (b.121-128), B theme with imitative counterpoint between piano and clarinet, transition to the Coda.
Coda (b.129-142), the first part of which is the Introduction section paired with the B theme on the clarinet, b.137-142 is the beginning of A but more conclusive, b.141-142 on the piano is the B theme.
