From this point onwards, in FE all ritenuto terms are incorrectly spelled as rittenuto (bars 78, 87, 100, 112 and 114, 123 and 133). It is very likely that this corresponds to the notation of [A], as the young Chopin wrote this indication this way several times – see e.g. Etudes, op. 10, in E no. 3, bars 16 and 53 or in F minor no. 9, bars 8 and 63 (in the Sonata in C minor, op. 4, mvt. IV we also find rittardando in bar 93). The errors were corrected in GE (everywhere) and partially in EE (only in bars 57 and 123).
