b. 74-77

composition: Op. 28 No. 24, Prelude in D minor

..

The initial version of the ending of the Prelude (which can be deciphered from under the crossings-out in A) differed quite significantly from the final one – the passage reached only D, and the piece ended an octave higher: . In that version, it is noteworthy that the passage contains e3, e2, e and E, but not e1.

The next version may have looked like the one presented below: . Eventually, Chopin forwent all the aforemen­tioned e notes (he only left E1, which was added later) and added B1, thus providing the general part of the passage with a homogeneous course, based on the b-a-f-d sequence.
