The baritone voice is typically written in the range from the second G below middle C to the G above middle C (G2–G4) although it can be extended at either end. However, the baritone voice is determined not only by its vocal range, but also by its timbre, which tends to be darker than that of the typical tenor voice. The following is a list of singers in various music genres and styles (most of which can be found on the List of popular music genres) who have been described as the best baritones.
