Learn to play this familiar song by Bach with your right hand alone, then you can add the automatic chords. This arrangement starts in the key of F Major, changes to C Major in measure 9, and back to F Major in measure 17.
Use correct fingering (the numbers between the treble and bass staves) and you will have a smooth melody.
The rhythm will be a 4/4 time. Begin ver-r-ry slowly .
When you can play it well slowly, then try it faster.
