I really liked this piece, but for some reason I just like Chopin in general, it makes me basically want to be a better piano player. This piece contains a lot of characteristic traits that are commonly found in his music, such as lyricism as far as melody, a push and pull or rubato as far as tempo, and interesting and unique harmonic structure.
At first it was a little hard differenciating between a phrase group or a double parallel period for the opening of the A theme. I think I have been so used to binary forms that I immediately wanted to call this an open continuous binary just by looking at the first period. However, it is actually a pretty clear ternary form. I ended up deciding that it had to be a double parallel period with asymmetrical phrases both ending on half cadences. There is a modulation to the dominant, and its hard for me to pinpoint exactly where it occurs but listening to the piece, it is definately something that you can hear. Over the course of the period, I felt like the rhythm was really played with, stretched, pulled and molded which was kind of a cool thing. The second half of the period doesn't feel as tonally sound to me as the opening, it ends on a strange cadence that gives an uneasy tone to the piece. The section ends though with what seems to be a cadential extension starting in mm. 18-19 which really gives a sense of finalization and was more tonally satisfying.
The B section is somewhat reminiscent of the A theme as far as a few rhythmic and harmonic motives go, and I was just happy to see it end on a PAC back in F# minor after the previous stint of harmonic instability.
The return of the A theme, the third and final section of the piece brings about a similar period structure, however, this time the periods seem to be contrasting rather than parallel. The phrases are also still asymmetric, but this time they are shortened by one measure each when compared with the initial introduction of the period in the very beginning of the piece. Again there is a cadential extension just like at the termination of the A theme before.
This is a cute little piece, and was enjoyable to delve into...
