b. 44-46

composition: Op. 10 No 11, Etude in E♭ major

..

In A in bars 44 and 46 only the first out of four necessary flats lowering d1/2 to d1/2 is included. In FE two missing signs were added, apart from the accidental in the R.H. in bar 46 (which, in turn, was added in FED). In the remaining editions the notation is correct.

Two quavers in A (→FEGE,EE)

Triplet in FED

..

The main text is the version written by Chopin in FED as an addition to the version of A (→FEGE,EE). We give priority to the entry to the pupils' copy, as this kind of variation of repeating phrases is very characteristic for Chopin; he would often introduce it in the last phase of composing or to already finished pieces (cf. the Mazurka in G minor, Op. 24 No. 1, bars 57 and 59). In this situation an additional argument is the analogy to bar 27. We add the  omitted in the entry, lowering d3 to d3.
