The chords uncle Jack was playing is 1 - Dm , 2 - Bb , 3 - F, 4 - C. So this would be Chords 6, 4, 1, 5 in the Key of F. More commonly represented in the order 1 5 6 4. So F, C, Dm, Bb. but you could start a song on any of the 4 chords and keep the pattern and It would sound a little different. Strum pattern helps a lot too. Great tutorial. also Hi Uncle Tics.
