This song has two flats in the key signature. That means we need to change every B to B-flat and every E to E-flat, except for places like measure 5 where the note is specifically marked as B-natural.
For most of this song you will want to reset the sustain pedal every two beats.
Notice in measure 34 how the right hand has an “extra” note at the exact moment that the left hand has a short rest. That’s because the right is helping the left hand out by playing the top notes of the pattern. You could play the entire arpeggio pattern with just the left hand, but I find it easier to get the right hand involved.
