Original: 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 Holländer , Wotan\/Der Wanderer in the Ring Cycle and Hans Sachs in Die Meistersinger von Nürnberg .
Simplified: A bass-baritone is a male singer whose voice is quite low , like a deep baritone , but not quite as low as really deep bass .
