b. 114

composition: (Op. 4), Sonata in C minor, Mvt IV

Wedge over b1-g2 in A, likely interpretation 

No mark in GE (→FE,EE,IE)

..

The notation of the 1st crotchet in A is ambiguous – it is uncertain whether the top note (g2) is supposed to be provided with a separate stem pointing upwards, as it was interpreted in GE (→FE,EE,IE), or whether this "stem" is actually a wedge over the sixth in one-part writing. To the main text we adopt the latter, yet the version of the editions can be considered an equal variant.

The clear staccato dot in A was recreated in GE and EE. FE has a wedge, it cannot be excluded that such a sign could have been in the lost base text. In the editions we generally have a situation in which the wedges written by Chopin were most frequently interpreted as dots.

A (→GE) and FE have the indication sotto voce. In A one can see that Chopin corrected the original indication – . Taking this into consideration, different indications in EE –  legatissimo – are almost certainly authentic and come from the lost manuscript base text (it also applies to the remaining indications in bars 117, 119, 122). In A we also have a few other deleted and corrected performance indications. Cf. also the beginning of the Mazurka Op. 24, No. 2.

In EE there should be an octave doubling of the note in the L.H. – such a notation could certainly be present in the base text of EE
