Bass-baritone 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 Holländer", Wotan/Der Wanderer in the "Ring Cycle" and Hans Sachs in "Die Meistersinger von Nürnberg". Wagner labelled these roles as "Hoher Bass" ("high bass")—see fach for more details.
Voice change A voice change or voice mutation, sometimes referred to as a voice break, commonly refers to the deepening of the voice of people as they reach puberty. Before puberty, boys and girls have roughly similar vocal pitch, but during puberty the male voice typically deepens an octave, while the female voice usually only deepens by a few notes.
