Rhythm

b. 18

composition: Op. 10 No 4, Etude in C♯ minor

..

In GE3 the e-e1 octave is a quaver, as a result of which the bar has only 7 quavers in the part of the L.H. The rhythmic error proves that the quaver flag in this place was printed by mistake.

b. 45

composition: Op. 10 No 4, Etude in C♯ minor

..

In AI the chord in the L.H. is written with semibreves (apart from the acrotchet in the upper voice).

Crotchet in FE (→EE)

..

In the main text we give the rhythm of FE (→EE), which probably represents the latest intention of Chopin, written in [A] or introduced in a proofreading of FE. The composer could have wanted to reinforce the return of the initial fragment of the piece (cf. the note on the accent). The dynamic and rhythmic motif of the last accentuated crotchet of the bar is one of the most characteristic sound phenomena of the Etude.

b. 63-65

composition: Op. 10 No 4, Etude in C♯ minor

Minims in AI

Dotted minims in FE (→GE,EE)

..

Same as in bars 13-15, the plain minims in AI are most probably an inaccurate notation of the final version.
