b. 83

composition: Op. 27 No 1, Nocturne in C# minor

Minim a1-a2 in GE

Dotted minim in FE

EE1 (→EE2)

Only a2 with a dot in EE3

..

The rhythm notation in GE, in which the rhythmic values of both marked voices of the R.H. add up to a dotted minim written in the L.H., is formally correct and makes musical and pianistic sense. There is no reason to doubt its compliance with [A]. Adding in FE (→EE1EE2) of the dots extending the octave a1-a2 is most probably the engraver's fault, as he failed to grasp that the minim d sharp 2 was supposed to sound on the 3rd beat of the bar together with g sharp1-f sharp2-g sharp2. The version of EE3, clearly erroneous, could have originated as a result of an unfinished attempt to restore the version of  GE.

First octave without accidentals in GE (→FEEE)

Chopin certainly regarded the pitch of the recitative's first octave as determined by before the minim b at the beginning of the bar. However, the rules of notation require accidentals before the octave as well, at least before its lower note. The inaccuracy was corrected by Chopin in FED.

No accidentals before 15th octave in GE (→FE)

Sharps restoring F-f in EE

Our suggestion

..

In GE (→FE) there are no sharps restoring F-f in the 10th octave of the quaver group. The F sound would be less natural on both melodic grounds (augmented second) and harmonic ones (the key of C minor). Omissions of that type are sometimes found in Chopin’s notation, cf. e.g. Etude in C minor Op. 10 No 12, bar 18. According to this we supplement sharps in the main text. The signs have been added in EE.

A long accent in GE

No sign in FE (→EE)

..

A short sign in GE, if only reproduced precisely after [A], is most probably a long accent. The lack of the sign in FE (→EE) is almost certainly an engraver's oversight.
