These double stop sixths sound amazing over this Bmi7 chord vamp. I'm sliding into the minor 6th to start and descending through a series of diatonic 6ths from the key of Bmi/Dma.
You'll see the triad shapes as I play through them. Letting the double stops sustain for the full note value sounds wonderful against the chord. Try re-phrasing this idea for additional licks.
