Pitch

b. 1

composition: WN 55, Waltz in F minor

 
 
..

In FEF and GEF, we give in brackets a tied a-cthird on the 1st beat in the L.H., which refers to the repetition of the whole Waltz in those sources.

b. 4

composition: WN 55, Waltz in F minor

 
 
 
 
 
..

In AG, the text of the chord on the 2nd beat in the L.H. is ambiguous. Most probably, it lacks in c1, while the dash visible in this place results from "restarting" the pen, which - by analysing the entire autograph - would often leave two thin dashes and a blank space between them instead of a homogenous, full dash. Chopin may have automatically written two dashes in this place, trying to "restart" the pen with quick movements.

b. 5

..

Almost all sources feature two b-c1-gchords. In AK, on the 3rd beat there is a crotchet rest instead of the chord.

b. 5

composition: WN 55, Waltz in F minor

..

In CC, there is no natural next to b1. It is one of a few mistakes-oversights of this type of the copyist in this source.

b. 5

composition: WN 55, Waltz in F minor

..

We add a cautionary flat next to b - like in AG (→CY).
