b. 14-15

composition: Op. 22, Andante spianato

No slur in sources

Slur suggested by the editors

b. 15

composition: Op. 22, Andante spianato

..

In the 2nd half of the bar the L.H. semiquavers are arranged in FE in a way that the last one falls already under f3 in the R.H. The inaccuracy was corrected both in GE and EE.
