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.
Metrical phonology Metrical phonology is a theory of stress or linguistic prominence. The innovative feature of this theory is that the prominence of a unit is defined relative to other units in the same phrase. For example, in the most common pronunciation of the phrase "doctors use penicillin" (if said out-of-the-blue), the syllable '-ci-' is the strongest or most stressed syllable in the phrase, but the syllable 'doc-' is more stressed than the syllable '-tors'. Previously, generative phonologists and the American Structuralists represented prosodic prominence as a feature that applied to individual phonemes (segments) or syllables.
