Bass (vocal range)

A bass (or basso in Italian) is a male 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). The Harvard Dictionary of Music defines the range as being from the E below low C to middle C (i.e. E2–C4). According to Singing for Dummies, bass range is normally F2 to E4 but can be as wide as Eb2 to F4. According to its author, Pamelia S. Phillips, the bass changes from chest voice into middle voice around A3 or Ab3 below middle C and changes into head voice around D4 or C#4 above Middle C. Phillips states that the bass's low voice is his strength, and the bass's high voice is his weakness. Phillips also states that the bass's voice is the deepest, darkest, and heaviest of the male voices.

It is also common for men who are classified as "basses" (and have a full bass choral range) to have a speaking voice which may sound much higher than would be expected. Most seasoned basses also can train a very versatile falsetto, making their usefulness in a choral arrangement even greater.

Bass roles in opera
