b. 70

composition: WN 17, Polonaise in B♭ major

In JC, the chords in the L.H. are written with ginstead of f1.

In the same manuscript, one can see a number of cautionary accidentals, which somehow remind about their validity: a  before ee1 and e4e3, a  before a2 and a  before f3. The flat before e1 on the 2nd quaver is also in PE.
