In Mendelssohn's 6 Kinderstücke Op. 72 No. 2 "Andante Sostenuto" (See the first 6 bars in the image below) there is the indication to play "sempre legato" and there are slurs as well.
Where does the "sempre legato" start? From the 3rd bar or from the 2nd?
Since the slurs imply: play legato, is this redundant with the "sempre legato"? If not, how should I play the slurs?
The edition I am looking at here is the RCM Level 8 List C - 2015 Piano Celebration Series.
Slurs are present in the score even after the 3rd bar for LH and RH.
