Guitar - How Do You Make Sounds With Strings?

When you play the cello, usually you're using a bow and not plucking it with your fingers or strumming it the way you might a guitar. So most of the time you're right, I am using the bow. It's a special kind of wood that you find in Brazil called Pernambuco wood. And then the wood is connected to, believe it or not, a bunch of horsehair. The hair from a horse's tail and it's white and we string it really tightly. And when we cross the strings, that's what makes sounds. Without a special thing on the horsehair, the horsehair by itself doesn't make sound.
