vocal and pitch range above bass and below tenor
A baritone is a man with a voice range between that of a tenor (high male voice) and bass (low male voice), typically ranging from the second F below middle C to the F above middle C. It is the most common male voice type.
Famous baritone roles in opera include: Papageno in Mozart's The Magic Flute and Figaro in Rossini's The Barber of Seville.
Dietrich Fischer-Dieskau is often thought of as the greatest baritone of the later 20th century. He was famous as a Lieder singer as well as on the concert stage and in opera.
Some musical instruments are also called "baritone" because they create similar frequencies to a baritone singer.
