Pitch

b. 5-7

composition: Op. 63 No. 3, Mazurka in C# minor

Lower register of accompaniment in FE1 (→GE)

Higher register of accompaniment in FE2 (→EEW)

..

The authenticity of the change of position of the accompanying chords and the bass register introduced in FE2 (→EE) is unquestionable. In a later version Chopin polished up the sequence of 3 voices contained in chords in the tenor and alto register and avoided a parallel shift of chords (G major→C minor) between bars 7 and 8.

composition: Op. 63 No. 3, Mazurka in C# minor

..

In FE (→EE) there is a  to the d quaver. As notes at this pitch are not subject to any alterations both before and after (until bar 32), in the main text we remove the unnecessary accidental. An identical revision was performed also by GE. According to us, the  may be a remaining element of the initial version of this motif, with d as the first quaver.
