Usually in piano music, the right hand is written in treble clef and the left hand is written in bass clef. However, the left hand changes to treble clef at measure 41. So to play this part, you can pretend that you’re playing two right hand parts.
For most of this song, you should reset the sustain pedal every two beats. There might be a few places where you want to hold it longer, but it’s up to you.
If you can, make the section at measure 33 a little bit faster than the rest of the song. This will add contrast to the song and help give it some momentum.
