*(I mistrust the word "development"; give me a "fantasia-development" that doesn't actually quote any of the movement's themes over a "developmental" repetition of themes that halts the piece in its tracks and misses the -dramatic- point of what the middle section's actually supposed to do- I'm looking at you, Dvorak symphony 9 finale e.g.- any day.)
