Is it perfectly acceptable to play just one movement of his sonata for the recital (not the solo recital by the way)? for example, like just doppio movimento....I know one should play the entire sonata....otherwise it wouldn't be complete. But it seems like his sonatas in general somewhat lack coherence among different movements so I thought maybe I could play just one movement as an individual piece. Can I make such an exception? Will this jeopardize the integrity of the piece?
You said that sonatas may "lack coherence among different movements," and that may be true to an extent, but how do you think the Funeral March became so popular?
