The final lesson in the series is a reel. As we are in the key of D left hand fingering is to use the first finger for the second fret, second for the third fret, third finger for the fourth fret, and fourth finger for the fifth fret.
The accompaniment is a little complicated. Tony uses a lot of D/F# chords. The chord of D contains three notes D, F#, and A, in any combination and in any number.
In the case of D/F# you finger the F# note on the 6th string.
Tony does this with his thumb, which is a bit controversial with the more conservative music teachers.
