b. 12

composition: Op. 28 No. 12, Prelude in G♯ minor

..

This bar was entirely crossed out in A and rewritten on adjacent staves – the R.H. above the crossing-out, while the L.H. – below. In the readable initial version, the regular steps of the R.H. quavers and the position of the 1st L.H. chord are preserved, while the f1 notes are written enharmonically as e1: . The corrections had been performed before the performance marks were introduced – the crossed-out version did not contain the following elements: accent, staccato dots, phrase mark, dashes marking the range of crescendo and pedalling marks. The  restoring b1 on the 3rd beat of the bar was also missing.

In the main text we add cautionary sharps before f1 and d2. The former was also added in EE.

The bottom note of the R.H. bottom voice on the 2nd crotchet is written too low in FC, as a result of which in GE1 it was interpreted as an e1. The patent mistake was corrected in GE2 (→GE3).

The  – added in FC most probably in pencil – lowering c2 to c2 is a later addition of H. Scholtz. It should be emphasized that it is highly unlikely that Chopin could have overlooked that  – such an oversight of an accidental defining the sound of a newly introduced key is absolutely uncommon in Chopin's music, let alone in the discussed place, since Chopin took care of precise notation by signalizing the return of g1 with a cautionary sharp, as it was g1 that was present in a few previous bars. Scholtz introduced the version with c2 – completely arbitrary – in the edition of the Preludes that he edited (Peters, Leipzig 1879); it was also popularized by certain later collective editions, e.g. edited by one of Chopin's pupils, Karol Mikuli (Kistner, Leipzig 1879) as well as by a few 20th-century urtexts (!). The reason could have been to avoid the cross-relation of c2 in b. 23 with c1 in b. 24; however, according to us, it is too weak an argument to interfere with the Chopinesque notation to such an extent. See also the note in the next bar.
