b. 102

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

A dot in A (→GE2GE3)

No dot in GE1 (→FEEE)

..

In A, Chopin entered a staccato dot on the 2nd beat of the bar, quite far from the note it was meant to refer to; this was probably why the dot was omitted from GE1 (→FEEE). It was supplemented in GE2 (→GE3).

In the sources there is no  before a1 (in the case of JC and PE it concerns bar 66, repeated here as bar 102). It is related to a different range of the octave sign at the beginning of the bar: the second semiquaver triplet is still embraced by it, which makes that the  at the pitch of a(in the notation) appears already before the 6th semiquaver of the bar.
