b. 49

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

..

Before the last pair of octaves in the L.H. there are no flats in A, as a result of which they should be read as A-a. Chopin's oversight, corrected already in GE1 (→FEEE, →GE2), is proved by the flats in the parts of all instruments performing the bass line visible in Morch.
