FE1 - First French edition
| Publisher: | Adolphe Catelin et Cie |
| Date: | VIII 1839 |
| Plate number: | Ad. C. (560) et Cie |
| Title: | 24 Préludes |
| Dedication: | Son ami Camille Pleyel |
First French edition based on A, in which the whole cycle of Preludes was divided in two books, 12 pieces each. Chopin did not participate in its preparation – proofreading of FE1, which included supplemented accidentals and pedaling, was conducted by Julian Fontana.
In the Prelude in D
major, FE1 repeated the inaccuracies of the chromatic notation of A – no 
in b. 12 or 2 marks in b. 75.
Other defects of FE1 include an omitted crotchet stem of g in b. 19, 
in b. 43 and 84 and accent in b. 87.
In FE1 certain minor inaccuracies of A were also corrected, e.g. a 
was added in b. 66 and 81, the number 9 was changed to 10 in the marking of an irregular group in b. 79.
In certain situations, the notation of FE is one of the possible interpretations of the inaccurate notation of A, e.g. slurs in b. 38-39 or 50-56.
One of the most significant differences between A and FE1 is the bottom note of the 1st chord in b. 70, which was raised by a second, thus changing the chord of A (of the span of a ninth) to a regular octave.
