Stash shows you the diatonic triads in the major scale, sometimes known as the harmonized major scale. He shows you how to create minor and diminished triads by modifying the major triad, and then shows you which kinds of triads correspond to each step of the major scale. He also shows you how to use these triads to play Norman Blake’s “Ginseng Sullivan” on the GBE string set in the key of D. In this video, Stash shows you how to construct the diatonic triads in the major scale, and then find them on the GBE string set in the key of D.
