Gavotte I by Bach

This Bach Gavotte is in simple binary form. The A section starts in g minor and ends on a PAC in B flat major at measure 8 and is repeated again. I believe this section is in open form because of the key change. When section B starts it seems d minor-ish because of the I in d at measure 9 but three measures later. The beginning rhythm is reminiscent of the one in the beginning A section but because of the different key and the developmental stuff going on through the rest of the section. I would also say it is transitional because of the key change back to Bb major then G minor ending the section with a PAC.
