b. 10

composition: Op. 12, Variations in B♭ major

Wedges in FE

Staccato dots in GE

No marks in EE

Crotchets suggested by the editors

..

Taking into account the e and f minims in the preceding bar and the absence of pedal markings, we assume that the most likely scenario is that the FE engraver mistook the crotchet stems (pointing upwards) prolonging g and g for wedges. In the main text we also move the legato indication, in this context most probably meant to indicate "harmonic legato". GE replacing wedges by staccato dots is a part of revision, encompassing the entire Variations – see the note in bar 7. The missing marks in EE are due to an oversight or revision.

In FE the  to the 11th semiquaver is missing, which is almost certainly an oversight, typical of Chopin. It was added both in GE and EE.

Quaver g in FE (→GE,EE)

Additional crotchet suggested by editors

..

In the main text we suggest prolonging the sound of the g tone on the basis of the following analysis and the rhythmic values and articulation of the bass notes in bars 7-14. Chopin indicated that the bass notes should be extended in the following ways:

  • with pedal in bars 7-8 and 11-12 and on the last beat of bar 13; the respective quavers are then provided with wedges;
  • by prolonging the rhythmic values in bar 9 and 13-14.

There are two exceptions: bar 10, in which wedges without pedal probably resulted from a misinterpretation of [A], and the discussed place, which is devoid of both longer rhythmic values and pedal, which we consider an oversight, by Chopin or by the FE engraver.
