Tuvans are famous for their throat singing. Throat singing is a very old art. And it is very special because a throat singer can sing two or more notes at the same time. Throat singers imitate the sounds of nature. They can sound like a bird or like the howling wind. One style of throat singing has a rhythm like a horse trotting. For many centuries only men were allowed to be throat singers. But now women are throat singers too. Singing more than one note at the same time is sometimes called overtone singing.
