Okinawa's signature musical instrument is the three-stringed sanshin. Its musical magic comes--not from the snakeskin covering, as many people believe--but from the wooden neck of the instrument. If the neck has the perfect balance of flexibility and solidity, the music will soar.
The perfect wood is ebony, a hardwood that is getting harder and harder to acquire. If you are thinking of making a sanshin, step # one is to plant a tree.
