Watch the Diatonic Chords Diads online guitar lesson by Stu Hamm from Stu Hamm U: Fretboard Fitness

Let's see where these major and minor chords come from by learning an exercise that takes us up the G and C major scales, playing the appropriate major or minor 10th. This should help you make sense of the tonalities of the various modes and see where the major or minor 10ths come from and if you are ever asked to play "Lean on Me" you'll be all set!
