e1 in chords in #CFI

d1-e1 in A (→FC→GE) & FE2 (→EE)

d1 in FE1
..

In the earlier version recorded in FCI, attention is drawn to  the absence of d1 notes in the L.H. chords of the 2nd half of the bar and the allocation of the last e1 to the R.H. On the other hand the absence of e1 notes in those chords is very probably an oversight by the engraver of FE1. The mistake was corrected in FE2 (→EE).

g1 in chords in A (→FC→GE), EE2 & FED

g1 in FE (→EE1)
..

The missing  lowering g1 to g1 is an oversight of the engraver of FE (→EE1). It was corrected only just in EE2, probably on the basis of a comparison with GE1. A flat was also added in FED.

b. 79-81

composition: Op. 28 No. 17, Prelude in A♭ major

..

At the beginning of b. 79, in FCI we can see a d2 crotchet combined with a tie to a d2 note in the previous bar, while the R.H. part is written down with the use of two-part notation already in this bar. A d2 crotchet is also at the beginning of b. 81, yet there is no d1, 1st bottom voice quaver.
