Issues : Terzverschreibung error
composition: Op. 24 No. 4, Mazurka in B♭ minor
At the beginning of the bar, A has the tenth a flat2-c flat4, which is an obvious mistake. That error was overlooked in GE1, as both in that edition and in the editions based on it, i.e. FE (→EE) and GE2 (→GE3), the correct octave a flat2-a flat3 appears.
