The transition of a dominant-seventh V chord to the I (tonic) chord is common in Western music in general, and ubiquitous in vernacular forms such as folk, blues, and bluegrass. A firm grasp of the options for building seventh chords and resolving them will make any guitarist a more versatile player. In this lesson, Grant shows you his method of creating three-note seventh chords by taking the major triad and either moving the root down to the seventh or moving the fifth up to the seventh. He shows you how to do this on A triads in all triad voicings and in numerous positions, as well as how to resolve the A7 voicings you’ve created to the nearest D major triad. He also shows you the A Mixolydian scale that corresponds to each A7 chord. In this video, you’ll learn to create three-note A7 voicings from A triad voicings.
