Pedalling

b. 29-38

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

..

In CDP there are no pedalling marks from bar 29 until the end of the piece. We do not consider it to be a real "variant" of indications and we do not include this source in the pedalling notes.

b. 30

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

No markings in AI

Pedalling in A (→GE), FE & EE

..

In this bar, last on the page, in AI there are no pedalling marks. It is certainly an oversight.

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

No markings in AI

 in A (→GE), FE & EE

..

Lack of pedal change in AI on the 2nd beat of bar 36 and 38 is an earlier version, completed by Chopin in A and repeated in this form in the remaining sources. Similarly in bars 40-41. In the entire final part of the Etude, in the final version, Chopin opted for rather more frequent pedal changes.

b. 37

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

 on 3rd beat in Ai

 on 2nd beat in A (→GE), FE & EE

..

In this and adjacent bars, AI presents a different pedalling concept. Subtle changes, introduced by Chopin in the version intended for publication, do not change the harmonic frame, yet they suggest a differently detailed phrasing of the melodic line. Similarly in bar 39.

b. 37

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

 in AI, A (→GE) & EE

Earlier  in FE

..

The too early placed  mark in FE is, according to us, a result of an error or misunderstanding.
