After Presto, in A one can see that the further part of the indication was crossed out, most probably con fuoco.

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.

under L.H. part in A

in FC (→GE) & FE (→EE)

..

According to us, the position of the  indication under the bottom stave in A does not mean that it refers to the L.H. only. Due to the above reason, in the main text we put it in its usual place, in accordance with the remaining sources.

c1, our alternative suggestion

..

The suggested version based on an A major chord can be considered an acceptable variant. The version was probably the initial one in A; Chopin then changed it to a version that does not sonically diverge from the next two bars. According to us, that change, however, could have been a result of a confusion: b. 24-25 could have been taken for b. 25-26.

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

..

Starting from the 2nd beat of b. 33, the R.H. part was enhanced by Chopin; he crossed out the earlier version, which we present below: . The changes consisted in making the bottom voice independent and in rejecting short slurs in favour of a longer phrase mark. Considerable corrections can also be seen in the following bars – see the notes to b. 36, 37-38 and 39
