I got a new shakuhachi this week. This one is made by Kodama Hiroyuki, who is a true master of both making and playing the instrument. You can learn more over at my shakuhachi website, where I have been chronicling my experience learning this Japanese flute.
This is the “root end” of the instrument. The bamboo is pulled out of the ground and cut, leaving some of the roots on while it dries, then the roots are cut off, leaving this attractive pattern around the bottom edge.
