b. 8-16

composition: Op. 30 No. 1, Mazurka in C minor

No marks in FE (→EE)

Long accents in FC

Short accents in GE

..

The accent in bar 8 entered into FC is undoubtedly a long accent. Therefore, it allows us to consider the less unambiguous accent placed in a similar context in bar 16 to be long too. Both marks were almost certainly added by Chopin. In GE all accents in this Mazurka are more or less of the same length, and we reproduce them as short.

b. 8-9

composition: Op. 30 No. 2, Mazurka in B minor

in bar 8 in FC (→GE)

in bar 9 in FE (→EE)

The difference in the position of  could result from the vague [A] notation, in which the mark was probably in the place of the bar line (Chopin would write separate bar lines on each stave). The musical context requires  to be introduced already from d2 in bar 8, hence in the main text we put it at the end of this bar, in accordance with FC (→GE).

In FE the last R.H. note is a crotchet, as a result of which the bar includes 7 quavers. In the main text we correct this mistake after the FC notation (→GE); this version is also in EE.

In As one can see a tie to the c1 minim in bar 8, sustaining it to the grace note in the next bar. Chopin eventually deleted it; however, it proves that he was considering this operation (not found in other pieces) – an unplayed grace note – and that it could have been used as diversification in bars 48-49 in the final version.
