b. 50

composition: (Op. 4), Sonata in C minor, Mvt I

Slur to crotchet in A

Slur to quaver in GE (→FE,EE,IE)

..

In the main text we provide the A slur, clearly led to the E-e crotchet at the beginning of the 2nd half of the bar. The shorter slur in the editions resulted from the inaccuracy of the engraver of GE or perhaps from a routine revision, adjusting the slur to a typical rhythmic group.
