"A bass-baritone is a high-lying bass or low-lying \"classical\" baritone voice type which shares certain qualities with the true baritone voice. The term arose in the late 19th century to describe the particular type of voice required to sing three Wagnerian roles: the Dutchman in Der fliegende Holl\u00E4nder, Wotan/Der Wanderer in the Ring Cycle and Hans Sachs in Die Meistersinger von N\u00FCrnberg."@en .
