Wikipedia: Tenor
Tenor is a type of classical male singing voice whose vocal range is between the countertenor and baritone voice types. The tenor’s vocal range (in choral music) lies between C3, the C one octave below middle C, and A4, the A above middle C. In solo work, this range extends up to C5, or “tenor high C”. The low extreme for tenors is roughly A♭2 (two A♭s below middle C). At the highest extreme, some tenors can sing up to two Fs above middle C (F5). The tenor voice type is generally divided into the leggero tenor, lyric tenor, spinto tenor, dramatic tenor, heldentenor, and tenor buffo or spieltenor.
