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.
Questions:
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.
