b. 3

composition: Op. 24 No. 1, Mazurka in G minor

..

In GE2 (→GE3) a cautionary  was added before a1 on the last chord. That unjustified revision was probably done to imitate Chopin's signs in analogous bars 11, 51 and 59.

composition: Op. 24 No. 1, Mazurka in G minor

Visible in A is the erased original version of the accompaniment, in which both bars had G crotchet with a staccato dot falling on the 1st beat. Both bars also had pedalling analogous to the pedalling preserved in adjoining bars. The notation before the change was as follows:

b. 3-7

composition: Op. 24 No. 3, Mazurka in A♭ major

..

In AI there is no slur in the L.H. part in bars 3 & 7. In the editors' opinion it is just an economical notation, for a corresponding slur is to be found in bar 1, which contains the same notes and rhythm as in the discussed bars. In the main text we give slurs found in A (→GEFEEE). Similarly in bars 27 & 31.
