Issues : Errors in the number of ledger lines

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

The chord in the R.H. on the 2nd beat of the bar was crossed out in A and rewritten to the left of the original position. It is possible to read the initial notation – it was a chord written in two parts with a c2-f2-acrotchet in the bottom voice and an eminim in the top one. One can see that Chopin wrote one line too many and in the proofread version he also resigned from the fnote.

A has an aas the last note in the L.H. It is almost certainly a mistake – cf. analogous figures in bars 300, 302 and 304-306. Mistakes in the number of ledger lines are the most frequent pitch errors committed by Chopin (excluding those related to the notation of accidentals). GE (→FEEE) features the correct text, which can be ascribed to Chopin's proofreading or a fortunate mistake, since there are no visible traces of correction in print, whereas the note in A, despite three ledger lines, is written lower than the previous g1.
In the discussed place, there is a visible correction in A. The deletions are actually very precise, yet their placement allows us to indicate e1 and das possibly crossed out original (or only erroneous) last two notes.
