The alto is the lowest type of female voice. The typical alto range lies between F3 to F5, though there are those who can sing above or below this range. Those who can sing below are often called “contralto’s” and can usually sing in a range similar to a tenor.

Though altos have a very similar range to mezzo-sopranos, their voices are usually richer and fuller in the lower register than mezzos. Again, it’s all about where the voice is most comfortable.
