b. 101-102

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

No fingering in A (→GEFE,IE)

Fingering in EE1

Fingering in EE2

..

In the main text we omit the inauthentic L.H. part fingering added by EE. The difference between the two EE impressions was caused by the fact that the authentic layout of the 2nd half of bar 101, in which the group of 4 L.H. quavers is written on the top stave (changed in the main text, yet kept in the transcriptions of the sources), confused the reviser preparing EE2. He assumed that the EE1 fingering, aptly suggesting that these quavers are to be performed by the L.H., was erroneous and changed it to the fingering adjusted to the R.H.

b. 101

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

No slur in sources

Slur suggested by the editors

..

In the main text we add a slur after analogous bar 103. Chopin, particularly in the early period of his oeuvre, would often try to write slurs from the side of noteheads, even in a several-part texture (cf., e.g. the A slurs concerning the R.H. quavers in bars 97-98 and 100). However, there were times when he would omit slurs that were too difficult to write due to the layout, as in the discussed situation or in bar 99.

in FE (→GE), contextual interpretation

rf in EE

..

In FE (→GE) we can see here "zf", which we change to the correct . The issue of the Chopinesque notation of forzato and its variants in other sources is discussed in detail in the note in bar 1. EE opted for a different version (arbitrarily), suggesting rf.
