EE1 - First English edition
| Publisher: | Wessel & Co. |
| Date: | I 1840 |
| Plate number: | (W & Co. No. 3099.) |
| Title: | Twenty four Grand Préludes through all Keys |
| Dedication: | His Friend Camille Pleyel |
First English edition in which the whole Op. 28 was divided into two fascicules bearing consecutive plate numbers (3098 & 3099), and containing respectively 14 and 10 preludes. EE1 is based on FE2, with some arbitrary revisions – see Prelude C no. 1. Chopin had no part in preparing the edition.
In the Prelude in F minor, flats restoring e
(1) at the end of b. 8 and naturals determining the sound of the last semiquaver in b. 12 as d(1) were added. Also added was an erroneous 
raising d2 to d2 in b. 3 (this was probably meant to be a cautionary 
). Few other mistakes were committed as well – slurs in bars 1-2 (over the pairs of chords) and in the 2nd half of bar 15.
The horizontal accents in b. 16 having been replaced with vertical ones is a revision typical of EE.
