The DIJBOW by Andy Graham
The DIJBOW is a one-stringed version of the Electric Stringed Didgeridoo. However, it is played primarily with a violin bow. It is shorter in length, creating a didgeridoo in the higher key of F, while the string is tuned to a very low F.
When the string is bowed at various harmonic nodes, it produces very eerie overtones that intertwine with the natural harmonics of the didge. The result is an amazing, trance-inducing wash of tones.

PLAYING TECHNIQUE :
The didgeridoo is played while the string is struck with a special steel rod in the left hand, or with a violin bow. A guitar slide is used on the right hand to bring out the harmonics along the nodes of the string.
