The park near my house is a collection point for old christmas trees to be recycled. Someone dumped a bunch of bamboo in the pile (christmas bamboo?) so I grabbed a stalk and let it dry for a month. This bamboo really wants to split – in fact, I can hear the flute spontaneously disintegrating in the other room.
This is a Native-American-style flute (two chambers, with an external air passage connecting the two) made with guidance from Sammy Tedder’s page.
It sounds like this.
