The Fantasia-Impromptu is a larger scale piece in a ternary form with a strongly contrasting middle section (Allegro giocoso in the outer sections, Andante Cantabile in the middle one). After a six-bar introduction, the principal theme enters in a double period in which both units end on the dominant. Here is the first:
After a contrasting middle of 19 bars, the theme returns, though now the second unit is entirely new -- but once again ends on the dominant):
Now this unit is repeated, finally closing the A-section in the tonic and introducing a transparent ascent from ^5 to ^8 in the cadence.
All this is repeated at the end of the piece, and a brief rousing coda follows:
Arlequin (n11) is a conventionally designed waltz set with a short introduction, four waltzes, and a coda that quotes the first waltz. It is unusual in the progression of keys: F-Bb-Eb-Ab and a return to F through a quick modulation in the coda.
The first strain of waltz n1 gives a prominent place to ^3 (A5) in the first unit, but the second runs a line directly from ^5 over a typical TSDT functional progression.
The second strain (trio) of n2 leaves little doubt about its attention to ^5, and ^6 as its neighbor.
