Melodic Minor Part 4: The augmented triad

Looking at the diatonic triads built on C Melodic Minor, we will find one augmented triad in the scale:

I min = Cmin
IImin = Dmin
bIIIaug = Ebaug
IV maj = F
V maj = G
VI dim = Adim
VII dim = Bdim

which is Eb+

The chord tones of the Eb augmented triad are:

Eb, G and B

Also, all the inversions of this triad will also be root position augmented triads from the lowest note, hence:

Eb aug = G aug = B aug

Symetrical relationships such as this are very useful for guitar players as they provide a great visual resourse for us in understanding and improvising over the scale. After all, 3 notes out of the 7 notes from the scale is a lot!

Ways to practice

1. Figure out two-octave fingerings for the aug triad, practice with metronome to develop fluency.
2. Figure out whole range of guitar fingering (3 octave plus) for all augmented triads. (Since all augmented triads have three possible roots, there are really only four augmented triads!)
3. Play different chords from the melodic minor scale and figure out the note relationship of the augmented triad to the chord you chose.

Till later, play on!
