Watch the A Minor Maj7 Chord Inversions online guitar lesson by Frank Vignola from Inversion Excursion
Now that you have a good grasp on the triads let's move on to adding extensions. We will now add the major 7th to the triad to make an A minor/major 7th chord. Remember: a minor triad is a three note chord consisting of the 1st, flat 3rd and 5th step of the applicable scale. In this case A, C and E spell the A minor triad. Adding an extension to the triad creates a 4 note chord. In this case we are adding the major 7th step to the triad. The major 7th step of the A harmonic minor scale is G#. The spelling of a A minor/major 7th chord is: A-C-E-G#. Let's start inverting. In this case, when playing the G# or major 7th in the bass, this is considered the 3rd inversion. Root position has root in the bass, 1st inversion has the 3rd in the bass, 2nd inversion has the 5th in the bass and the 3rd inversion has the extension or in this case the 6th in the bass. For each inversion, look at the chord and pick out each of the chord tones naming the notes.
