Wedges in A

Dots in GE (→FE)

Absence of any signs in EE

b. 42-43

composition: Op. 24 No. 4, Mazurka in B♭ minor

A long accent in bar 42 in A

An accent in bar 43 in GE1 (→FE)

No accent mark in EE

A short accent in GE2 (→GE3)

..

An accent under the syncopated octave f2-f3 in bar 42, longer than usual here in A, was printed at the beginning of bar 43 in GE1 (→FE). In EE the accent was omitted altogether, which is probably an error. In GE2 (→GE3) the accent returned to its proper place, but in the form of an ordinary short accent instead of a long one.
