b. 89-91

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

The slurs of  A (interpreted in context)

Literal reading of A (→GE1FEEE)

Another slur added in GE2 (→GE3)

The editors' proposed version

..

In A, the course of writing was interrupted both between bars 89-90 (by the deleted fragment) and between bars 90-91 (by passing on to a new line of the text) .This has caused unclear and unnecessarily complicated notation of the slurs.
