A tenor is a type of classical male singing voice whose vocal range is one of the highest of the male voice types. The tenor's vocal range lies between C3, the C one octave below middle C, and, the A above middle C. In solo work, this range extends up to, or "tenor high C." The low extreme for tenors is roughly A♭2. At the highest extreme, some tenors can sing up to two Fs above middle C. The term tenor is also applied to instruments, such as the tenor saxophone, to indicate their range in relation to other instruments of the same group. Within opera, the lowest note in the standard tenor repertoire is A2, but few roles fall below C3. The high extreme: a few tenor roles in the standard repertoire call for a "tenor C". Some of the few top Cs in the standard operatic repertoire are either optional or interpolated by tradition. However, the highest demanded note in the standard tenor operatic repertoire is D5. Some operatic roles for tenors require a darker timbre and fewer high notes. In the leggero repertoire the highest note is F5, therefore, very few tenors can, given the raising of pitch since its composition, have this role in their repertoire without transposition. A shift in pitch since the mid 19th century means that the few written top Cs would have in fact demanded a note at least a semitone lower than today's standard pitch. Wikipedia [ - ]
