b. 149

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

In FE (→GE1), the last 8 notes are written as 2 groups of semiquavers. The division into groups suggests that Chopin meant a strict and regular division, so the notes should be demisemiquavers. A respective change was introduced in EE and GE2 (→GE3). Additional beams were added also in FEJ, although it is impossible to confirm the authenticity of such a non-characteristic entry.

Fontana's fingering, natural in this context, is probably compliant with the one foreseen by Chopin – cf. a Chopinesque indication in a similar passage in bar 141.

In FE, there is no  raising d1 to d1, which must be considered an inaccuracy, since dpreviously appeared only on the bottom stave. The mark was added in GE and EE, whereas in the latter, a  was repeated also before d2.

According to us, the likelihood of the authenticity of Fontana's fingering in EE is minimal. In EE1, it clearly contains a mistake – the 3-5 sequence under the 4th and 5th semiquavers is very inconvenient. The mistake was corrected in EE2 (→EE3), changing the digit under gto a '4'. However, it seems to be more likely that Fontana projected the fingers 3-4 for these notes in order to avoid the 5th finger on the black key – the use of the regular scheme 512451... would not have required such a detailed marking; it would have been enough to repeat 51 at the beginning of the subsequent groups of semiquavers, like in bars 142-143.
