B Minor Sixth chord (Bm6) on the guitar fretboard

The B Minor Sixth chord (Bm6) is made of B (the root), D (minor third), F# (perfect fifth) and G# (major sixth). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the chord.

The minor sixth adds a major sixth to the minor triad, which keeps the dark third and lifts the top note. Its four notes repeat across the neck and share a shape with the half diminished chord on a different root. It sits next to the minor triad and the minor seventh.
