My latest Dronitar is a 3 stringed, 2-motored, piezo contact pickup’ed instrument made from plywood and a strip of hardwood from a doorframe!
The frets are positioned so that it can only play the same notes as a Tempered Hang, this was in the brief for the commission. This makes it very easy to play within a set scale and have each string/fret on the same scale. Making it hard to not play harmoniously! (no offense Rich!)
