Ranjit Bhatnagar of Moonmilk was so inspired when he saw a 99-cent coconut at the supermarket that he bought it and made this awesome one-string coconut banjo!
The frets are bamboo skewers - I tuned them by ear so the tuning is kind of shaky. I might add more frets later. Note how the bamboo bridge rests on a point on the membrane (architectural vellum)- this helps to transfer the vibrations of the string.
