In Lesson 20, you learnt to play the D7 chord using the F#, C and D notes. Here is a different way of playing D7 which uses the A, C and D notes. To play D7 in this way, use the first, second and fourth fingers of your left hand.
This song contains the new D7 fingering in bars 5 and 13.
On the recording there are three beats to introduce this song.
