b. 44-45

composition: Op. 50 No. 3, Mazurka in C♯ minor

Double bar line in AI & AF (→FEEE)

Single bar line in GE

..

According to us, the double bar line in AI is a trace of change of the key signature for it to correspond to the key of B major; a trace that was left by inadvertence. It is indicated by the absence of such a bar line in GE – Chopin apparently considered it superfluous while writing [AG], in spite of the fact that a new section of different nature begins here. In this situation, the double bar line in AF (→FEEE) may be explained by the composer's distraction at the time of copying the Mazurka – a reassessment of this issue, although possible, seems to be less likely.

b. 133-136

composition: Op. 50 No. 3, Mazurka in C♯ minor

..

AI is missing b. 133-136 (as well as preceding b. 105-132) – a counterpart of b. 137 and the continuation of the Mazurka follow after b. 104. In the transcription of AI we provide this final fragment with double numeration, i.e. 105-160, which corresponds to the contents of this autograph, and 137-192, which corresponds to the final version.
