P.D.Q. Bach Prussian Sonata No. 1

This piece appears to be in some sort of Sonata-Allegro-ish form. LAST BLOG!
Bach opens the piece in F major, ending group 1 at the beginning of bar 6 on a PAC. We immediately find ourselves in a transitional section, where Bach flirts briefly with d minor, but moves to the dominant key of c major. There is something of an authentic cadence in the 9th measure, but it quickly moves on to transitional phrase ending on a IAC in c minor. A little more transition and we find ourselves after a half cadence in c major to group 2 in bar 24, lasting 8 measures till 31. Nothing too weird yet.
The developmental section is very...developmental??? It begins with developing group 1, which lasts from measures 32-42ish. This section is very tonally ambiguous. It's hard to pin down a key, there are b naturals, b flats, e flats and naturals, f sharps, g sharps. It's a little crazy. Around measure 6, we see material from the group 2. In measure 55, there is a large half cadence. This would be as expected...however it's a half cadence in the dominant key. There is no re-transition period. WEIRD. Actually, it's not that weird, it just makes the piece sound very abrupt in change, almost like a sonata-rondo. Instead of staying in the tonic key of F major throught the transition to from group 1 to group 2, Bach insists in flirting with C major and minor. Never fear, in measure 75, we hear our group 2 in the right key of F major, ending the piece on a nice PAC. Whew. PS No coda.

Good job mentioning the key changes. Also, nice use of the word flirt. I agree that the developmental section is hard to figure out.

Good job with pointing out the deviations from the forms we've learned earlier. The point of this last chapter is some things don't fit any of the standard forms we've learned but still have some structural divisions and similarities to standard forms.

i agree... good job with the structural divisions. this chapter was kind of confusing

Nice, I liked how you remarked that instead of the usual HC back into the retransition it was in the dominant--how that gives a more additive and disconnected feel.
