Before playing songs with chords, practice each part separately. First practice the melody of the song by itself (right hand part), then practice the chords by themselves (left hand part). Once you have learned both parts, play them together. Practice slowly and evenly, and count as you play. The part containing the chords is called the accompaniment.
This song is the main theme to Beethoven’s 9th Symphony. It contains all the notes and chords you have learned so far and has two chords in bar 8.
