Watch the Week 7: Triad PowerUp online guitar lesson by Joe Pinnavaia from Triad Powerup
This week's lesson is about triads that are really an interval of a 3rd apart. These actually create extended harmony arpeggios because they outline the main harmony of the scale/chord while adding intervals above the octave. Take D minor as an example. The notes would start off as D, F, A then F, A, C then A, C, E then C, E, G then E, G, B. These combinations give us not only D minor 7 but also add 6, 9, and 11. Cool sounds against a D minor7 chord.
