b. 287-288

composition: Op. 2, Variations, complete

..

In AsI and A, accidentals were put only next to the top notes of the octaves – a  to a in bar 287 and naturals to e3e and a  to g in bar 288. All necessary accidentals were already added by GE (→FE,EE).

b. 288-291

composition: Op. 39, Scherzo in C♯ minor

Slur in EE and FE

No slur GC (→GE)

..

Absence of the slur in GC (→GE) is probably the result of the copyist's accidental omission.

b. 288-289

composition: Op. 39, Scherzo in C♯ minor

d tied in GE

No tie in EE, GC & FE

..

The tie sustaining d in GE is probably an arbitrary addition, made by analogy with bars 156-157.

b. 288

composition: Op. 21, Concerto in F minor, Mvt I

..

In A (→GE1FE) there are no accidentals in the last group of semiquavers. In EE the necessary  returning fon the last semiquaver was added, whereas in GE2 and EE3 two cautionary flats at the beginning of this group, before b2 and a(in the main text we include only the first one).

b. 288

composition: Op. 21, Concerto in F minor, Mvt I

3 slurs in A, probable interpretation

2 slurs in A (possible interpretation) & GE2

1 slur in GE1 (→FEEE)

..

Combining the slurs over the rest in bar 288, as it was done in GE1 (→FEEE), may be considered to be justified in this case – the slurs in A look like an inaccurately written one slur. In GE2 the manuscript was interpreted correctly. In turn, in the very A the slurring of the junction of the bars, which are written on adjacent pages, is unclear. The slur in bar 288 suggests a continuation, which is not excluded at all by the slur in bar 289. However, when discussed separately, the second slur seems to be a typical slur combining a grace note with a semiquaver associated with it, hence we consider such an interpretation to be more likely and we adopt it as the text of A and the main text.
