Watch the A Dorian Mode online guitar lesson by Brad Carlton from Guitar Lab: Dorian Dominance

This lesson presents the diatonic seventh chords that exist in the A Dorian mode. I've presented them in two ways. The parent of A Dorian is G major which means that a G major scale played from A to A would be the A Dorian mode. The major scale always has the following diatonic chord construction off each scale degree: major seventh chords off the first and fourth scale degrees, dominant seventh chords off the fifth scale degree, minor seven chords off the second, third, and sixth scale degrees, and finally minor 7b5 chords off the seventh degree of the scale. All of the even-numbered diagrams beginning with diagram 44 and finishing with diagram 58 display these four diatonic seventh chord qualities on the fingerboard in the key of G. They will always follow the same sequence as you move up the scale. The odd-numbered diagrams beginning with diagram 45 and finishing with diagram 59 reveal what scale degrees will result as you play these chords/arpeggios in an A Dorian tonality.

These diatonic seventh chords are presented in root position, first inversion, second inversion, and third inversion. They are also presented in two layouts on the fingerboard: the top four strings and the middle four strings.
