J.S. Bach – “Gavotte 1” from English Suite No. 3 in G minor

Gavotte No. 1 is written in g minor with no structural phenomena other than the double bar lines dividing sections A and B. The piece is written in g minor – there are no marked changes in key signature.

The A section encompasses measures 1 through 8, and is repeated. This section is a parallel, symmetric period, with the antecedent phrase ending in the middle of measure four on an IAC, and the consequent phrase ending on a PAC in measure 8, tonicizing the relative major key, Bb Major. I would consider the A section open or continuous, in that it modulates to Bb Major. The A section is expository.

The B section appears to tonicize d minor right away, evidence of structural division that is not obvious at first glance. The B section is a phrase group that is repeated, and is definitely tonally unstable. It expands upon themes from the A section, so it must be developmental. There is a PAC in d minor at measure 18. There is a cadence at measure 26 that is a little more ambiguous to me, since it occurs so quickly. It seems to be a HC in g minor, meaning that we’ve returned to the tonic key. The final cadence is, of course, a PAC in g minor.

Good work.

The development section is a bit confusing. One of the easiest ways to study this is by looking at the accidentals. The cadence in measure 18 is on the d minor but soon afterword the F sharp creeps back in which means the transition has been made back to g minor, though the heavy tonicization of the V chord does give a slight feeling of D major
