b. 11

composition: Op. 64 No 1, Waltz in D♭ major

a in chords in As, AI, AII & AIII

No a in A (→FEGE,EE)

..

In the previous autographs, the bar is an exact repetition of bar 9.

b. 11

composition: Op. 35, Sonata in B♭ minor, Mvt I

 in GC and FE (→EE)

Longer  in GE

..

The  hairpin in GE begins earlier than in the remaining sources. Such an adjustment of a sign to an entire bar is a typical inaccuracy of GE.

b. 11-12

composition: Op. 21, Concerto in F minor, Mvt II

Continuous slur in A (→GE)

Separate slurs in FE (→EE)

..

The separated slurs in FE (→EE) are most probably an inaccuracy repeated after the proof copy of GE1. In the very GE1 (→GE2) the slur was corrected (combined) in the last phase of proofreading, perhaps by Chopin.

b. 11

composition: Op. 21, Concerto in F minor, Mvt III

Sixth in A & GE2

f2 in GE1

a1-f2 in FE (→EE)

..

The a1-fgrace note is written inaccurately in A – the fragment of the stem combining both notes of the sixth is missing. It most probably contributed to the omission of the bottom note, a1, in GE1. The mistake was corrected by Chopin in FE (→EE) analogously to bar 27, a solution we adopt in the main text. The version of A can be considered an equal variant, since, although being earlier, it was never directly replaced by Chopin.

Fingering written into FED

No teaching fingering

..

The same fingering is written in FED twice, in bars 81 and 83. The digits written by Chopin were probably overwritten by the pupil, so that they were more visible.
