b. 1-23

composition: Op. 28 No. 17, Prelude in A♭ major

..

The text of FCI, containing an earlier version of the Prelude, differs, more or less, from the remaining sources. In further comments, we take into account the versions of FCI only where they may influence the interpretation of A and the determination of the main text; in a few cases, also where they constitute musically interesting alternative solutions with respect to the main text, yet consistent with the version intended for printing.

b. 1-2

composition: Op. 28 No. 17, Prelude in A♭ major

..

To write down these bars in A, Chopin used repeat marks – / to mark the L.H. part in the 2nd half of b. 1 and / in b. 2. In FC repeat marks were used only in b. 2. The highest number of repeat marks is to be found here in FCI – all those visible in A as well as / instead of the R.H. part in the 2nd half of b. 1.

b. 4-18

composition: Op. 28 No. 17, Prelude in A♭ major

..

The majority of the groups of repeated quavers were written in A (→FCGE) as dotted crotchets provided with quaver tremolos. In A this is how the L.H. in the 2nd half of b. 4, 5, 7, 10-13 and 18 and the R.H. in the 2nd half of b. 10 were marked. A similar situation occurs in FC (→GE) – except b. 18. Such notation is not observed at all in FCI.

b. 11-16

composition: Op. 28 No. 17, Prelude in A♭ major

..

These bars are marked in FCI in an abridged manner as a repetition of b. 3-8. The version of this fragment (appearing twice) differs both from b. 3-8 and 11-16 of the final version; however, the differences concern textural issues only – position and density of chords as well as assignment of notes to the right or left hand.

b. 19-21

composition: Op. 28 No. 17, Prelude in A♭ major

..

In A (→FCGE) the topmost notes of the L.H. part (d1 and higher) are written on the top stave, while in b. 19 the R.H. g notes are placed on the bottom stave:

 (the accidentals and the order of the overlapping quavers in the right and left hands are presented according to A; in FC the  before E was omitted, and GE supple­mented accidentals and introduced some changes in the horizontal arrangement of chords). In FE (→EE) this seemingly illegible notation was simplified by placing the part of each of the hands on a separate stave, which we also adopted to the main text. According to us, the complexity of the original notation resulted in the double Terzverschreibung mistake in b. 21 in GE.
