Do you know anything'bout "Sanba," not samba. Most probably have no idea. Sanba is a musical instrument popular in Okinawa. It's said their folk songs often use Sanba.
Sanba means three boards in Japanese. It consists of three planks and a string as you can see. To say frankly, apart from whether your rhythmic sense is good or wrong, we're almost difficult to find a person who cannot deal with the instrument.
Now, in other words, it's just like a castanet of Okinawa. Castanets came from Spain and Sanba from Okinawa. They say they use ebonies and oaks for making the Sanba. Some say that plywood can also work. It means anybody can make and enjoy the musical instrument easily.
Watching a motion picture below, you can learn how to play. Like playing castanets, I'd like you to play and enjoy Sanba comfortably. When you are tripping to Okinawa, it could perhaps be a help to get familiar with the native mood.
