b. 21-29

composition: Op. 28 No. 22, Prelude in G minor

In the 2nd half of b. 21, A (→FC) places an unjustified  before d2, but omits a  raising f1 to f1. Equally in b. 29 which in the manuscripts is only marked as a repetition of b. 21. The overlooked  was added in all editions except FE in b. 29. In both bars EE removed the unnecessary , we include this revision in the main text.
