A bass is a male singer who sings in the lowest vocal range.
According to Grove Music Online, a bass is typically classified as having a range extending from around the F below small C to the E above middle C (i.e., F2–E4), with a tessitura, or comfortable range, normally ranging between the outermost lines of the bass clef.
However, cultural influence and individual variation create a wide variation in range and quality of bass singers. Parts for basses have included notes as low as the C two octaves below middle C (i.e. Measure 12 of Ne Imami Iniya Pomoshchi by Pavel Chesnokov), and the Rachmaninov Vespers call for the B-flat a tone below that. Many basses have trouble reaching those notes, and the use of them in works by Slavic composers has led to the colloquial term "Russian bass" for an exceptionally deep-ranged basso profondo that can easily sing these notes. Some traditional Russian religious music calls for A2 (110 Hz) drone singing, which is doubled by A1 (55 Hz) in the rare occasion that a choir includes exceptionally gifted singers who can produce this very lowest of human voice pitches.
In choral music, voices are subdivided into first bass and second bass, no distinction being made between bass and baritone voices, in contrast to the three-fold (tenor-baritone-bass) categorization of solo voices. The exception is in arrangements for male choir (TTBB) and barbershop quartets (TLBB), which sometimes label the lowest two parts baritone and bass.
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.citation needed
In classical music, and particularly in opera, the following distinctions are often made among different kinds of bass voices:
Basso Cantante/Lyric High Bass/Lyric Bass-baritone
Basso Cantante means 'singing bass'.[3]Basso cantante is a higher, more lyrical voice. It is produced by a more Italianate vocal production with a faster vibrato. A lyric bass-baritone.
Buffo, literally "funny," basses are lyrical roles but demand a solid coloratura technique. They are usually the antagonist or the comic relief in Bel Canto operas.
Basso profundo, is the lowest bass voice type. According to J. B. Steane in "Voices, Singers & Critics", the basso profundo voice «derives from a method of tone-production that elimintes the more Italian quick vibrato. In its place is a kind of tonal solidity, a wall-like front, which may nevertheless prove susceptible to the other kind of vibrato, the slow beat or dreaded wobble».
