b. 80

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

..

The indication accelerando is written in the sources in an abbreviated form: acceller. in GE (→FE), and accel. in EE. We delete the superfluous second 'l', and in the main text we change the seldom used Chopin's abbreviation for the full indication.

b. 80-81

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

Double bar line in GE (→FEEE)

Our suggestion

..

The sources have a double bar line before the change of key. However, we do not include it in our main text, as it is almost certainly an arbitrary addition of the engraver of GE (→FEEE).

b. 81

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

..

In the first chord of bar 81 we add the following cautionary accidentals: a natural for a2 and the sharps for d1, f1.

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

Hairpins in GE

FE (→EE)

..

In GE, bar 81 is the last bar of the system. In this situation, a new  sign in bar 82 could, in Chopin's times, mean the continuation of the previous one and this is how it was understood in FE (→EE). We adopt that interpretation as definitely matching the musical sense of that fragment.

b. 83

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

Bar line in GE

No bar line in FE (→EE)

..

The irregular notation of GE is nevertheless clear and most probably authentic which is why we give it in the main text. We also regard Chopin's intervention during the proofreading of FE as a very unlikely explanation of the lack of bar line in FE (→EE).
