A - Autograph
| Date: | IX 1832-III 1833 |
| Title: | Nro 10 |
| Dedication: | None |
Autograph fair copy intended as Stichvorlage for the first French edition. It creates an integral part with the autograph of two previous Etudes in F major, No. 8 and F minor, No. 9. At the moment of its creation, it probably constituted a part of a joint autograph, including six subsequent Etudes, from No. 7 onwards – see the characteristics of A of the Etude in C major, No. 7, where the issue of dating of this manuscript is also briefly discussed.
In A one can see numerous engraver's marks, determining the division into pages and great staves of FE1.
A includes quite a significant number of corrections, in which the removed elements are generally carefully erased, e.g., in bars 2, 4, 8, 17, 21-23, 29, 34, 51-52, 76. Deletions are less frequent, e.g., the change of the number from 9 to 10 in the heading of the Etude, changes in the part of the L.H. in bars 37-38 and 44. In spite of these changes, some details remained in a non-final form, which Chopin then changed in a proofreading of FE, e.g., the accentuation in bars 1-8 and 17-20, harmony in the 1st half of bar 68.
Chopin provided the Etude with numerous and detailed performance indications. However, their notation is not always precise, which can be seen on the example of slurs (bars 55-56 or 75-76). It can indicate haste at the time of writing, which is also visible in the reduction of the graphical form of some of the marks, which almost borders on a draft nature, e.g., the 
in bar 5 and the presence of characteristic "hooks" at the bottom of the stems or naturals, e.g., in bar 5 (cf. the characteristics of the autograph of the Mazurka in C major, Op. 24 No. 2). The fingering and pedalling are marked only in a few characteristic places – the fingering at the beginning of the Etude and in bars 9 and 54, pedalling in bars 1-4, 27, 43-49 and 54-56.
A is lacking numerous accidentals, e.g., in bars 5-8, 37-38 or 40. Moreover, it is not free from other mistakes, as the octave sign in bar 43, which was led too far or – probably – the octave instead of a sixth at the end of bar 39.
