Chaminade, Piece Romantique, Op. 9n1

Chaminade, Piéce Romantique, Op. 9n1 (1880).   The design is ABA, where A is a 16-bar theme closing on V rather than I--see below-- and is then repeated, B is briefly contrasting but turns out to be an 8-bar transition, and A is an altered reprise of the theme with a close on the tonic.

Here is the altered reprise.
