composition: Op. 28 No. 15, Prelude in D♭ major

In A one can see that the first two quavers in b. 11 were crossed out; they were initially f2-d2. It was also a tie to the former, running from b. 10, that was crossed out. It is probably a correction of an erroneously introduced fragment of b. 14-15.

b. 11-17

composition: Op. 28 No. 15, Prelude in D♭ major

In A one can see that Chopin was reducing the range of the accompanying figures in b. 11 and 17. In particular, he moved the bass note in the 2nd half of b. 11 an octave higher: , while in b. 17, which was initially identical to b. 15, he replaced both bass F notes with dyads in the middle register.
