Op. 28 No. 17, Prelude in A♭ major
This bar is absent in FCI, which could be seen as one more example of haplography – cf. the versions of FC in the Prelude in G minor no. 12, b. 78-79 or in B
major no. 21, b. 54. However, according to us, this version keeping a regular, two-bar gap also between the last strokes of the bass A
1 (in FCI it is not repeated anymore in b. 88) suggests that this is the initial version, expanded later by Chopin:
- he added a stroke of the bass note in b. 88 while gradually reducing its frequency;
- he improved the combination of the main theme of the Prelude with the ending by repeating the motif twice as a calming factor, first to a two-bar section (b. 79-80 and 81-82) and then one-bar section (b. 82 and 83).
