b. 17

composition: Op. 28 No. 12, Prelude in G♯ minor

d1 in A (→FC,FEEE) & GE2 (→GE3)

e1 in GE1

..

The version of GE1 must result from the engraver's mistake.

under L.H. part in A

in FC (→GE) & FE (→EE)

..

According to us, the position of the  indication under the bottom stave in A does not mean that it refers to the L.H. only. Due to the above reason, in the main text we put it in its usual place, in accordance with the remaining sources.

b. 21-22

composition: Op. 28 No. 12, Prelude in G♯ minor

4 slurs in A (→FC), contextual interpretation

2 slurs in FE (→EE)

3 slurs in GE

..

The double slur of A (→FC) in b. 21 and the abridged notation of the R.H. part in b. 22 posed problems to the engravers, as far as the interpretation is concerned. In the case of b. 21, the top one is a tenuto slur, sometimes used by Chopin even for single notes, which was not a common practice in his time. FE considered it a slur for the entire R.H. part and omitted the bottom slur, whereas GE stretched it to the next bar, which resulted in an ambiguous curved line – a slur or a tie of b1. In b. 22 there is only a / mark on the stave, yet Chopin wrote the top slur above it, which, according to us, does not mean that he forwent the bottom one; however, the editions interpreted it so.
See also b. 25-26.

b. 21-22

composition: Op. 28 No. 12, Prelude in G♯ minor

B tied in A (→FCGE) & EE2

repeated in FE (→EE1)

..

The missing tie of B is either a mistake of the engraver of FE or a liberal interpretation – initially, it was also f that was tied in A, yet Chopin crossed out that tie, which, considering the staccato dot over the B-f fifth, could be regarded as an inaccurately marked abandonment of both ties. The tie was added in EE2 probably after GE1.

b. 21-22

composition: Op. 28 No. 12, Prelude in G♯ minor

4 staccato dots in A (→FEEE)

Dots in bar 21 in FC

No marks in GE

..

The missing staccato dots in FC in b. 22 and in GE, in both bars, are probably an oversight of the copyist and of the engraver.
