Analysis of prokofiev no10 from visions fugitives op 22?

Answer 1

The humor implied by the heading, Ridicolosamente, clearly places No. 10 in the
grotesque line. The "ridiculous" quality comes from the pairing of the incessant
accompanimental pattern with the humorous repetition of the slurred two-note motives in the right hand. A vague yet identifiable key center of G-flat is established in the first two measures. As the left hand pattern continues softly on a first inversion G-flat chord, the right hand plays a sharply contrasting F-natural. At this point it becomes unclear whether the piece is in G-flat major or B-flat minor.
As the piece progresses, new motives consisting of augmented harmonies are introduced (measure 11). An unusual cadence based on the tritone occurs in measures 20-21 and at the end in measures 37-38: E dom. 7th to B-flat minor. A stroke of genius by Prokofiev in measures 36-37 results in a halt of the incessant rhythm before concluding with five brief beats on a I-IV-V-I cadence in B-flat minor.
3rds are a prominent factor in the makeup of No. 10. The left hand pattern is almost
always in 3rds. Prokofiev also continues the pattern in this particular set of starting the
piece with harmonies based on a 7th: the F-natural in measure 3 against the G-flat
harmonic backdrop. As in No. 5, the disjunct melodic element creates a humorous effect.
