Not exactly a tone poem, but I wonder what people may think of Strauss'
Burlesque.  I really like it, and don't know why it is dismissed as
juvenilia.  In fact, listening to it recently made me think about how
so many authors do their best work early in their career, while the
early works of composers sometimes are discounted.

Burlesque doesn't really fit any structural category like tone poem or
concerto, but it offers and interesting motive which is developed in
various ways by the piano.
