Grace notes in the form of small crotchets are probably a mistake of FE (see e.g. Sonata in B
minor, Op. 35, mov. I, bar 208) – Chopin would use this kind of grace notes before longer rhythmic values, minims, semibreves (cf. e.g. Concerto in F minor, Op. 21, mov. I, bar 208). The revisers of GE and EE also evaluated it like that; both introduced forms of grace notes may be considered to be potentially compliant with the notation of [A]. In the main text, we adopt slashed quavers, most frequently used by Chopin.
