It is more often high voices that hog the limelight. Almost all male pop singers are tenors or sing in falsetto. Mercifully, songs can be moved to whatever key the singer chooses. Check out the most popular pop songs today at Billboard.com.
A bass (or basso in Italian) is a singer who sings in the deepest vocal range of the human voice. According to Grove Music Online, a bass has a range extending from around the F below low C to the E above middle C (i.e., F2 E4).
