The digit 1, which in this context means that the f
note should be taken over by the L.H., was ignored both by the copyist and the engraver of FE. A similar situation can be found in analogous b. 395, which makes us assume that Chopin could have added those digits in A already after having drawn up FC. See also b. 374. This is the only example of a silent takeover of a tied note by the other hand by means of fingering in Chopin's output. In a few other situations, the takeover was indicated by a corresponding rhythmic notation (the Nocturne in E major, Op. 62 No. 2, b. 35 & 73) or by a combination of vertical slurs before the chord (the Sonata in B minor, I mov., b. 103).
