it's the thing in the guy's right hand, what appeared to be flexible wires in a wooden handle. I didn't touch it.That's what I thought but didn't see anything in the picture that you would use to brush them to make the maraca like sound.
So I thought maybe they were for making mango zest, lol.
That's the sound I am accustomed to. To me it has a maraca like sound when the player brushes the guira, as opposed to when it is hit.kind of. but maybe more like a car puttering out or a tire losing air?
