composition: Op. 30 No. 4, Mazurka in C# minor

in FC (→GE)

legato in FE (→EE)

Our variant suggestion

..

It is difficult to say how the difference in the indications at the beginning of the piece occurred. As legato was not being removed in FC, it was probably added by Chopin in the stage of proofreading FE or to the basis thereof. One of these scenarios presented an opportunity for a possible removal of , which in FC seems to have been written in Fontana's hand. Due to the above, in the main text we suggest it in a variant form (in brackets). See also bars 13 and 33.

In FEcor Chopin added staccato dots also under the semiquavers of the lower voice in the R.H. (in bar 4 only under the first one). In a later proofreading he changed his mind, so that in FE (→GEEE) the dots are eventually absent. The staccato signs are also absent in Ap, in which they would be, however, contrary to the longer rhythmic values of the described two-note chords.

Triad & fifth in CLI

Triads in Ap & FE (→GE,EE)

..

The fifth on the 3rd beat of bars 2 and 6 in CLI is probably the original version. The c1 notes were originally absent also in FE, as in both bars Chopin added them in FEcor. Chopin hesitated in which places to put the cautionary naturals before c1, which can already be seen in FEcor, where before the triad on the 2nd beat of bar 2, a  was written and then deleted. Eventually, FE (→EE2EE3) has a sign before the triad on the 3rd beat of the bar, which we adopt to the main text in all analogous bars. GE1 (→GE1a) has a  before the 1st triad in both bars, while in the later editions arbitrary additions were also performed in this respect.

In the middle of the bar in FEcor there is no  raising c3 into c3. This obvious mistake was corrected by Chopin in one of the later proofreadings.

No naturals in CLI, Ap & FEcor

Naturals in FE (→GE,EE

Our suggestion

..

In bars 2 and 6 in one of the last proofreadings of FE (→GE,EE) cautionary naturals before c2 in the chord at the end of the bar were added. According to us, accidentals in those places are actually unjustified, yet due to their probable authenticity, we suggest to consider the first of them.
