b. 4-8

No slur in AI

A slur in A (→GEFEEE)

..

There are no slurs in the L.H. in bars 4 and 8 of  AI, Chopin wrote them later in A. We include those slurs in our text, just like it was done in all the first editions. In A, Chopin also added slurs in bars 28 and 32.

Slur in EE and FE

Slur in GE

Differences in the slur scope are probably the result of Chopin's inaccurate notation in the autograph (or autographs). As all the sources are unanimous in a similar situation found in bars 12-14, we are allowed to consider the slur of GE as best reflecting the composer's intention.

GE & EE

..

The placement of the  mark in FE1 literally means that the pedal should be depressed on the last beat of bar 4, which for harmonic reasons could not be intended by Chopin. Such notation probably results from misunderstanding the autograph, in which the mark might have been placed that way due to lack of space under the very low note (C1) in bar 5. The notation of FE2, in which bar 4 ends a line of text, is definitely erroneous. EE and GE have the  placed correctly in bar 5.
