b. 2

composition: Op. 10 No 2, Etude in A minor

..

In the middle of the bar in FEcor there is no  raising c3 into c3. This obvious mistake was corrected by Chopin in one of the later proofreadings.

Our suggestion

..

In bars 2 and 6 in one of the last proofreadings of FE (→GE,EE) cautionary naturals before c2 in the chord at the end of the bar were added. According to us, accidentals in those places are actually unjustified, yet due to their probable authenticity, we suggest to consider the first of them.

..

Lack of the  returning b2 on the penultimate semiquaver in bars 2 and 6 is most probably an inaccuracy of the notation of CLI. In bar 2 Chopin added the sign in FEcor, in bar 6 – probably already in the handwritten base text for FE.

Semiquavers in CLIFE (→GE,EE

Semiquavers & crotchets in Ap

..

In Ap the rhythmic values of subsequent two-note chords of the lower voice in the R.H. create in those bars (as well as in subsequent repetitions) an alternating short-long scheme (semiquaver-crotchet). Sometimes the resounding length contrast is additionally underlined with accents. In the main text we give the homogenous, as far as the sound is concerned, version of FE (→GE,EE).

Possible long accent in Ap

..

It is not clear how to understand the signs shaped in the form of accents visible in Ap at the end of bars 3 and 4. Therefore, in both places we offer alternative interpretations. A similar problem appears in analogous bars 11-12, 38 and 39.
