In the first lesson on triads and inversions Stash begins by showing you the chromatic scale on the low A string, beginning with the open E string and moving up fret-by-fret to the 12th fret. Then he shows you the three different diatonic triad shapes for G, C, and D chords on the DGB string set and how to use them to play the traditional song “Lonesome Valley.” He also explains that these shapes are different inversions of a major triad, and how to find the three inversions up the neck for G, C, and D chords on the DGB string set.
