1 measure of Intro.
Exposition mm.2-mm.69, transition from mm.65-69
Development mm.72-mm.211, mm.72-90 seems to be alternating between minor and major tonalities, however, I could not determine which tonalities or keys.
First theme is seen again in mm.85, mm.146
Basic structure of this piece is ABA Sonata Form.
Again, many changes of tonal center.
