The slur of AI reflects the original assumptions underlying the phrasing – it encompasses exactly 4 bars. In A, Chopin encompassed the entire first phrase with a slur, which, however, was not precisely reproduced in FE (→GE1op,GE1no2,EEC), perhaps due to the line of the text ending in bar 68. In subsequent editions, the slur was extended according to the musical sense.
