Bass-baritone

A bass-baritone is a singing voice that shares certain qualities of both the baritone and the bass. The term arose in the late 19th century to describe the particular type of voice required to sing Wagnerian bass roles like Wotan (in the Ring Cycle) and Hans Sachs (in Die Meistersinger von Nürnberg). Wagner wrote those roles for what he called Hoher Bass ("high bass").

The bass-baritone voice is distinguished by two attributes. First, it must be capable of singing comfortably in a baritonal tessitura. It must also, however, have the resonant lower range typically associated with the bass. For example, the role of Wotan in Die Walküre covers the range from the F# above middle C to the F below the bass clef but only infrequently descends beyond the C below middle C.
