Now for the chords.
The chords change in the song, at the exact same time the keyboard moves to the next chord,so if you are having trouble with the changes just re-listen to the song. The changes are illustrated by the placement of the chord letter above the word that the changes falls on. If your singing the song, you will know where the chord changes based on what word the chord is above.
