Rhythm

b. 26

composition: Op. 10 No 8, Etude in F major

Semibreve in A

Minim in FE (→GE,EE)

..

Adding to the remaining elements of the chord is almost certainly a result of a misunderstanding of the notation of A by the engraver of FE (→GE,EE).

b. 29

composition: Op. 10 No 8, Etude in F major

Minim in A

Semibreve in FE (→GE,EE)

..

The minim is most probably the original version, left in A due to distraction. To the main text we adopt the semibreve, being probably a result of Chopin's proofreading of FE (→GE,EE).

b. 31

composition: Op. 10 No 8, Etude in F major

Semibreve in A & GE

Minim in FE (→EE3)

..

The version of A and GE is undoubtedly correct. The single-voice notation of FE (→EE3) is probably a result of a misunderstanding of the autograph's notation. The division into two voices without changing the rhythmic values is certainly a result of the revision of EE4 (similarly in bar 63).

b. 47-49

composition: Op. 10 No 8, Etude in F major

Dotted minims in A

Minims in FE (→GE,EE)

..

Various rhythmic values of the elements of the A1-A octave in bars 47 and 49, marked in details in A, were not reproduced in FE (→GE,EE). Most probably, it is a result of misunderstanding of the manuscript. However, it should be emphasised that the pedalling added in a proofreading of FE makes the longer detention of the upper note a purely technical action, without any impact on sound.

b. 48

composition: Op. 10 No 8, Etude in F major

Semibreves in A (→FEEE3)

Minims in GE2 (→GE3GE4) & EE4

..

Change of the rhythmic value of the A-d fourth is an arbitrary decision of the reviser of GE2 (→GE3GE4) and EE4.
