b. 26

composition: Op. 12, Variations in B♭ major

Without slur or wedge in FE

Slur & staccato dot in GE

Slur & wedge in EE

..

In FE the second rhythmic group in the L.H. part is provided neither with a slur nor with a wedge, which is either the engraver's oversight or Chopin's inadvertence. The marks were added in GE and EE, yet in GE the wedge was changed to a staccato dot as part of general revision – see the note in bar 20.

In the main text we add cautionary accidentals – naturals to d3 and d2 in the L.H. part and a  to e3 and a  to a2 in the R.H. part. On the other hand, we omit the poorly justified  to a1 at the end of bar 27, present in all sources.

The absence of a  at the end of a piece (in this case, Introduction) is quite a frequent phenomenon in Chopin's works. Generally, it means that the pedal should be pressed throughout the entire final fragment or that it should be gradually released (the so-called diminuendo pedal). According to us, in the discussed case, holding the pedal pressed to the end results in a very good sound effect; alternatively, the pedal can be gradually released throughout bar 31 to be pressed again (optionally) in bar 32.
