The Chapman Stick is a kind of wide-fretted electric guitar with 10-12 strings that allow for the performer to play the melody as well as the accompaniment simultaneously. It was invented in the 70’s by jazz musician Emmett Chapman. Because it’s electronically amplified, there’s no need to pluck the strings; merely placing your fingers on them makes a sound for you. Different pressures and touches on the strings change the tone and volume of the sound, making it especially complicated. Because of this, not many people have mastered the instrument, and it remains fairly obscure. Robert Culbertson in the video above is one of the few skilled musicians that can show the full potential of the Chapman Stick.
