Wagner labelled these roles as "Hoher Bass" ("high bass")see fach for more details. - A baritone is a type of classical male singing voice whose vocal range lies between the bass and the tenor voice types. It is the most common male voice. Originally from the Greek , meaning "deep (or heavy) sounding", music for this voice is typically written in the range from the second F below middle C to the F above middle C (i.e. FF) in choral music, and from the second A below middle C to the A above middle C (A to A) in operatic music, but can be extended at either end.
