Slur beginning in A

GE1 (→FEEE)

GE2 (→GE3)

The slur in A begins on a semiquaver, along with the melodic narrative. In GE1 (→FEEE) it begins over the dotted crotchet, and in GE2 (→GE3) it starts at the beginning of the bar.

b. 125

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

A probable interpretation of the accent in A

Possible reading of the accent in A (→GEFEEE)

..

The type of accent intended by Chopin is not clear. A long accent seems more probable when we compare that bar to the analogous bar 117. GE (→FEEE) have a short accent here.

b. 127-128

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

A probable reading of A (→GE)

A possible reading of  A

FE (→EE1EE2)

..

A (→GE) has triads as the 2nd and the 3rd crotchets of those bars, although in the first triad in bar 127 the note c1 is practically invisible in the manuscript. When proofing FE, Chopin removed the middle notes of the triads leaving only the sixths. That corrected version was repeated in EE1 (→EE2). EE3 returned to the version of GE1 with the full triads (the omitted note b flat on the 2nd beat of bar 128 must be a mistake).

b. 127

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

The indication written in A as ritenuto was shortened to riten. in GE (→FEEE). In EE, the abbreviation was placed between the staves.
