b. 41

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

The sources display the lower note of the octave E-e in an inaccurate or mistaken way. In GE the note-head is placed on the correct height but there is no ledger line, and FE (→EE) simply give F here.

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

FE (→EE) and GE2

GE1 has no sharps before the last two quavers. It may correspond to the notation of [A] for Chopin certainly regarded as obvious the sharpening of notes that actually repeat the bass note written with already at the beginning of bar. The error was corrected in FE (→EE), possibly by Chopin, sharps were also supplemented in GE2.

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

No sign before d in GE (→FE

A flat before d in EE

A cautionary added in EE may be regarded as justified by the simultaneous occurence of d2 in the R.H. However, in the editors' opinion it is not necessary in this context.
