b. 5-15

composition: Op. 49, Fantaisie in F minor

..

In bars 5 and 15, opening new lines, the endings of some slurs/ties from the previous bars were omitted in FE – of the slur in bar 5 and of the slur and of the tie to a1 in bar 15. The inaccuracies did not mislead the engraver/reviser of EE, which includes the correct notation.

b. 6

composition: Op. 29, Impromptu in A♭ major

..

The crescendo hairpins are marked slightly different in each of the sources. The right-hand end of the hairpins in A is unclear. Comparison with analogous bars and FE and EE versions (out of which one is most probably based on a different autograph), enables considering A's notation as inaccurate. We harmonise the notation according to analogous places.

Accent in EE

..

The accent in EE is certainly an arbitrary addition by the publisher, introduced by analogy with an authentic accent in similar bar 89.

A less probable interpretation of A (→GEFEEE)

In the sources, bar 7 begins a new line of text; in such situations it is difficult to decide in Chopin's autographs whether the slur is to be treated as a new sign or a continuation of the previous one.
