b. 30

composition: Op. 28 No. 19, Prelude in E♭ major

..

A and the remaining sources contain 3 poorly justified cautionary accidentals in this bar – flats before e1 and e2 and a  before f2. We omit them in the main text; in turn, we add a  raising g1 to g1, which is necessary and which was overlooked in A. The sharp was added both in FC (→GE) and FE (→EE).
Moreover, FE overlooked the  raising f to f, which was corrected in EE.

No crotchets in FE (→EE) & GE

The crotchet stems, separating the sequence of the middle L.H. voice in A, were not reproduced correctly in any of the remaining sources. In the main text we give the notation of A.
