In the main text we give the metronome marking introduced by Chopin in a proofing of FE (→GE,EE). The slightly faster tempo than the one written by Chopin in A is compatible with the rhythmic changes in a few fragments of the Etude – in bars 27, 30 and 32 Chopin withdrew from the use of demisemiquavers.

In the main text we give the title and dedication in the undoubtedly authentic version adopted in FE. The extensions of both the title (in GE and EE) and dedication (in EE) most probably come from the editors. See the Etude in C major, No. 1, bar 1.

We give the time signature after A. Although FE (→GE,EE) displays , it is, however, difficult to assume that the change of time signature was intentional if in FE the  was not used in Etudes even once (contrary to the manuscripts), cf. the Etude in C major, No. 1, C minor, No. 4 and F major, No. 8. The phenomenon also applies to other pieces, even in the most obvious cases, e.g., in the Etude in F minor, Op. 25 No. 2, D major, Op. 25 No. 8 or F minor, Dbop. 36 No. 1.

In the main text we give the suggestive and explicit vertical accent of A. It is hard to determine whether substituting it in FE (→GE,EE) with a common accent was a result of Chopin's intervention or of the engraver's inaccuracy.

In A the indication legatissimo is written in an abbreviated form: legatiss. In the main text we follow the version of the editions.
