G to Bb is a minor third (3 semitones), Bb to D is a major third (4 semitones), D to E is a major second (2 semitones). A minor triad plus the major sixth, E. The sixth and the minor third Bb are a tritone apart, which gives the chord its dark, unresolved colour. With E in the bass the same four keys read as Em7b5.

Gm6 on the guitar

Standard tuning (E A D G B E). Strings run low E on the left to high e on the right, frets downwards; × is a muted string, ○ an open string, and each dot shows the note it sounds, with the root in blue-green. Every shape below has G as its lowest note.

The E-shape and A-shape grips are movable: an E-shape chord's root is the note under your first finger on the low E string, an A-shape chord's root is the note on the A string. Slide the same grip up or down to play minor sixth chords on other roots.

Inversions of Gm6

An inversion puts a note other than the root in the bass. The name is what semicord's chord finder calls those notes played bottom to top; a slash name like C/E means a C chord with E in the bass.

Where Gm6 fits

Gm6 is ii6 in F major, iv6 in D minor, i6 in G minor. As i6 it is the tonic chord of a minor key when the melody uses the raised sixth of the melodic minor scale, E; many jazz tunes in minor end on it rather than on Gm7.
