thing 23: rotten stick tension guitar
Detail: coconut sound radiatior.
Continuing to explore the variable tension theme from yesterday: the rotten stick tension guitar uses a hand lever to stretch the string and thus set the pitch. I had that bit of coconut leftover from the banjo, so I used it as a sound radiator. The walnut on the other end is for comfort when you prop the guitar up against your belly (the recommended playing posture).
It sounds kind of like this.
