Issues : Omission of current key accidentals

b. 50

composition: Op. 64 No 1, Waltz in D♭ major

..

The naturals raising g to g in the chord in the L.H. and g2 to g2 in the R.H. are not carefully written in the autographs – the sign in the L.H. is not present in any of them, while the sign in the R.H. is included only in AII and AIII. The signs were added in the proofreading of FE (→GE,EE), probably by Chopin.
