b. 61-62

composition: Op. 11, Concerto in E minor, Mvt I

Slur from 2nd beat in Atut (→FE)

Slur from 1st beat in GE

Slur from 3rd beat in EE

..

It is difficult to say what the reason for a later beginning of the slur in EE was. In turn, an earlier beginning in GE may be related to an inaccurately placed slur in FE, slightly too early, and to a comparison with analogous bar 69.

b. 62-71

composition: Op. 11, Concerto in E minor, Mvt I

..

In bars 62-63 and 70-71, the piano reduction written in Atut (→FEGE,EE) does not include the crotchet present in FEorch (→GEorch), serving as an upbeat to the bass line of the cellos.

b1 repeated in Atut (→FEGE)

Nothing indicates that the ties sustaining the bcrotchets in bars 65-66 and 73-74 could have come from Chopin. Theoretically, they could have been added by Fontana, who could perhaps recall Chopin's performances; this possibility allows for qualifying this version as, at most, a variant of questionable authenticity. If the composer wanted to sustain these notes, it would be difficult to explain why he did not mark it while writing Atut, proofreading FE (at least twice) or listening to pupils' performances.
The reviser of EE could have remained under the influence of the tie in bars 234-235; however, in that case the theme's melody is developed in a variational manner to a significant extent, so that moving such a detail from one version to another is out of the question (cf. the explicit repetition of the note in bars 226-227).

b. 68-72

composition: Op. 11, Concerto in E minor, Mvt I

..

In Atut (→FE), the minims in bars 68 and 72 are devoid of extending dots, which, in both cases, must be considered a mistake. Dots were added in GE and EE.
