Crotchets in AI

Quavers in FE (→GE,EE)

..

Probably in [A], or perhaps only just while proofreading FE1, Chopin changed the rhythmic notation of the first eight-bar section – he replaced the crotchets at the beginning of bar 1, 3, 5 and 7 with quavers filled with quaver rests. In the remaining three similar phrases he left crotchets (bar 9, 11, 13, 15, 69, 71, 73, 75, 77, 79, 81 and 83). According to us, such a change is probably to be regarded as a clarification of performance, marked the first time but generally valid in all these places. See also bar 3
