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, i. a. the fingering added in this and few other preludes (nos 3, 5, 6, 13, 21 and 24). Chopin had no part in preparing the edition.
The fingering digits added in this Prelude are fairly abundant – ca. one hundred digits in nearly 30 bars. Moreover, in EE1 a careful revision of accidentals was carried out:
- necessary accidentals were supplemented, e.g. in b. 6, 12, 18-20,
- cautionary accidentals were added, e.g. in b. 5 or 44,
- unjustified accidentals were removed, e.g. in b. 6.
Mistakes were not avoided in the process – a mistaken 
raising e
1 to e1 was added in b. 43.
EE1 overlooked few elements of notation: 
in the 2nd R.H. chord in b. 31 and a group of markings in bars 38-39 – an accent, a L.H. slur and a wedge.
