Minor 6th

Many chords have characteristic sounds, sounds that you can easily relate. It is for example easy to distinguish between the half diminished (m7b5) or the maj7. When I was studying for grade exams several years ago, I struggled to relate to the min6 as it is rare in most guitarists repertoire.

I leaned about Django Reinhardt and his style of playing years ago, but I never learned much of his tunes.

What follows is an extensive collection of Django Reinhardt sheet music. 

This would appeal mostly to jazz lovers, gypsy guitarists. Certainly not what I usually listen to.

What I instantly note is the frequent use of the min6 chord. I have only played a dozen of the pieces but I am loving it very much.  

My chord of the week is Gmin6

  

the easiest voice of this chord bares resemblance to a ordinary G Maj caged chord. 

From a caged Gmaj. Bring up the 3rd/4th fingers up (from e & b strings) to b & g string. Lower your 2nd finger ( from the 'b' note 2nd fret, A string) to the 'e' note 2nd fret, D string. Then you have a Gmin6. This is a 5 note voicing, I would recommend, not doubling up the octave. I mostly only play 4 note voicings for any chord. Many players would refrain from playing the octave, root, and the fifth. Sonic wise a bass player would cover responsibility of playing these notes. The important note left is the 6th (e) and the 3rd (Bb) which determines whether the chord is major or minor.
