b. 12

in A (→FEEE)

No sign in FC (→GE)

..

The lack of the  hairpin in FC (→GE) is Fontana's error.

b. 12

In A (→FC,FE) there is no  lowering e to e in the last L.H. figure. The patent inaccuracy was corrected in GE and EE.

b. 12-16

composition: Op. 28 No. 7, Prelude in A major

2 slurs in A (→FC), literal reading

2 slurs in FE (→EE) & GE

Slur in CXI

No slurs in CGS

..

In A (→FC) the last phrase mark of the Prelude also encompasses the final rest. It may be an inaccuracy, quite frequently encountered in Chopin's works, as it was interpreted in the editions; this is also the interpretation we give in the main text. However, it cannot be ruled out that such an ending of the phrase mark emphasizes the gradual dispersal of music, like the crossed-out pedal release mark. No division between the phrase marks in b. 14 in CXI can be explained by a misinterpretation of the Stichvorlage – the phrase marks of A are written with a flourish, which could have also been the case of the hypothetical manuscript that served as the Stichvorlage for CXI (Fontana committed a similar mistake in FC – see b. 6). The fact that the phrase mark was led to the end of b. 16, like in A (→FC), but unlike in the editions, is also noteworthy.
The missing phrase marks in CGS are most probably an oversight of the copyist.

b. 12

composition: Op. 28 No. 9, Prelude in E major

Tie in A (→FC,FEEE) & CGS

Slur in GE

..

In GE the tie of B was erroneously reproduced as a motivic slur combining B-E.

b. 12

composition: Op. 28 No. 9, Prelude in E major

tied in A (→FCGE) & EE2

repeated in FE (→EE1) & CGS

..

The missing tie of b must be an oversight of the engraver of FE (→EE1). The absence of that tie in CGS is one of the arguments proving that the copy comes from FE. The tie in EE2 was most probably drawn from GE1.
