b. 1

composition: Op. 25 No 1, Etude in A♭ major

A in AI

A1 in A (→CDP,GE), FE & EE

..

A greater schematic approach is generally characteristic for original versions, in this case AI. Lowering some bass notes or doubling them during the works on a piece is characteristic for Chopin – cf., e.g., the Etude in D major, No. 8, bars 25-26Etude in D major, Dbop. 36 No. 3, bars 55-59, Waltz in A major, Op. 42, bar 31 and 273, Polonaise in E minor, Op. 26 No. 2, bars 103-104

See also the note to bar 36.

b. 6

composition: Op. 25 No 1, Etude in A♭ major

..

In all manuscripts, FE and EE1 (→EE2) have no flats returning e2 and e1. This inaccuracy, so characteristic for Chopin, was corrected only in GE and EE3.

b. 7

composition: Op. 25 No 1, Etude in A♭ major

6 times b in AI

6 times a in A (→CDP,GE), FE & EE

..

In the first three figures the L.H. in AI has a b as the 3rd and 5th semiquavers. It is an earlier version, changed by Chopin still before writing A, in which the eventual version – with a – is already written in the final form.

b. 7-8

composition: Op. 25 No 1, Etude in A♭ major

A (→CDP,GE), FE & EE

..

In AI in both bars the 3rd figure in the R.H. preserves the regular melodic shape, i.e. the last two notes of the sextuplet are the same as the second and third note. Chopin changed it in A (→GE), correcting the already written original version. The remaining sources also include the final version.
