b. 1

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

Allegretto quasi Andantino in FCI

Allegretto in A (→FCGE, →FEEE)

..

According to us, the fact that the more specific tempo indication was abandoned in the final version of the Prelude may mean that the shape of the piece had crystallized – the double indication of FCI actually introduces an element of uncertainty, which suspends the tempo of the piece somewhere between Allegretto and Andantino.

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.

category imprint: Graphic ambiguousness; Differences between sources

b. 1-6

composition: Op. 28 No. 18, Prelude in F minor

4 slurs in A (→FC) & EE2

Slurs in b. 1, 2, 6 in FE

Slurs in b. 1, 2, 5 in GE

Slur in b. 6 in EE1

..

None of the editions based on manuscripts reproduced all 4 slurs over the pairs of chords in bars 1-2 and 5-6. EE1 overlooked yet 2 out of 3 slurs in FE. The complete set of slurs in EE2 results from a compilation of the slur of EE1 with the slurs reproduced from GE1.

b. 1-2

composition: Op. 28 No. 8, Prelude in F♯ minor

..

FE erroneously gives d instead of c as the last L.H. quaver in each of these bars. The errors, caused probably by this note in bar 1 being written somewhat imprecisely in A (bar 2 is marked as a repetition of bar 1 in the manuscripts), were corrected in FE2 (→EE).
