You can listen to yesterday and today’s work on the B section of the bassoon quintet here.
I think it’s not long enough. I think I could make it into a major development section, or use it as the second theme for an actual sonata allegro movement. I barely get the theme stated when I dismantle it and build to a screeching climax (from which I will ratchet it up even more until it collapses back into the claustrophobic A section.) I think it’s not enough.
However, if my goal is to have something for students to read on Friday, and it is, then we’ll just go with it as a first draft.
