A tenor singer is a type of classical male singing voice whose vocal range lies between the countertenor and baritone voice types. It is the highest male chest voice type and is positioned between the lower baritone voice and the higher countertenor. The typical tenor vocal range is C3–B4, which is the highest male voice type you will find in a typical choir. The tenor is the voice type with the smallest range, barely covering two octaves. In opera, the primo uomo, which is the leading man or main character, is most often a tenor. There are many vocal shades to the lyric tenor group, and the repertoire should be selected according to the weight, colors, and timbre of the voice. Different tenor voices can be divided into further subtypes depending on the context, such as the lyric, spinto, dramatic, and heldentenor, also known as the heroic tenor. Some well-known tenors in classical music and opera include Andrea Bocelli, Luciano Pavarotti, and Plácido Domingo, while famous male singers with a vocal range of tenor include Freddie Mercury of Queen, Bruce Dickinson of Iron Maiden, Bono from U2, Chester Bennington of Linkin Park, and Michael Jackson.
