Minim & crotchet in FE (→GE,EE)

Dotted minim in A

..

The g1 dotted minim present in A in the top voice of the L.H. is the original version – Chopin changed it in the proofreading of FE1 to an a1 minim and a g1 crotchet.

composition: Op. 26 No 1, Polonaise in C♯ minor

A-B in A, FE2 (→EE) & GE5

A-B suggested by the editors

A-B in FE1

A-B in GE1 (→GE2)

A-H in GE3 (→GE4)

..

The oversight of  in FE1 (→EE) next to the second grace note could have been caused by the unclear notation of A – due to the cramped notation of grace notes (probably added later)  is almost illegible. The correct version was returned in FE2 (→EE), most probably as a result of Chopin's correction. In GE1 (→GE2) the clearly erroneous version of FE1 was revised, by changing the 1st grace note to A. Another revision was performed in GE3 (→GE4), by deleting the  next to the 1st grace note. The correct text was introduced only in GE5, probably after comparison with FE2.

In the main text we remove the unnecessary  next to the minim, most probably being a trace of the original version without the grace notes beginning the trill.

Staccato dot in A & GE

No mark in FE (→EE)

..

Same as in bar 7, the absence of the staccato dot in FE may be a result of Chopin's proofreading. The presence of the dot in GE seems to be a revision (inaccuracy?) of the engraver.
