b. 276

composition: Op. 21, Concerto in F minor, Mvt I

..

Same as in analogous bar 128, in A there is no accidental before the crotchet in the middle voice. It must be an oversight, corrected already in GE1 (→FEEE, →GE2).

Long R.H. accent in A (literal reading→GEFE)

R.H. short accent in EE

L.H. long accent in A, interpretation suggested by the editors

..

Same as in bar 130, we consider that it is more likely that the accent refers to the L.H.

In the part of the R.H. A (→GE1FE) has only one , before the 2nd semiquaver. The necessary signs for the b2 and bnotes were added in the remaining editions.

Crotchet c1 in A (literal reading→GEFEEE)

No crotchet in A (contextual interpretation)

..

The alleged additional crotchet stem next to cvisible in A is, according to us, an exceptionally imposing trace of Chopin's reflex at the time of writing notes on ledger lines. In order to secure visibility of such a note, the composer would give the note head the shape of a vertical line – see analogous note in bar 303. Sometimes, particularly when writing in haste (as in this case), the lines were long enough to look like a crotchet stem pointing downwards (a slightly shorter line in bar 301 did not mislead the engraver). See also the Etude in F major, Op. 10 No. 8, bars 4-7

In A (→GEFE) there are no naturals before the dnotes (in both hands) and d3. In EE two of them were added (apart from din the R.H.).
