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, sung mostly in Rossinian Andrea Nozzari’s roles, but also in other composers’ operas (Mime, Herod). The high extreme: a few tenor roles in the standard repertoire call for a “tenor C” (C5, one octave above middle C). Some (if not all) of the few top Cs in the standard operatic repertoire are either optional (such as in “Che gelida manina” in Puccini’s La bohème) or interpolated (added) by tradition (such as in “Di quella pira” from Verdi’s Il trovatore). However, the highest demanded note in the standard tenor operatic repertoire is D5 (“Mes amis, écoutez l’histoire”, from Adolph Adams’ Le postillon de Lonjumeau). Some operatic roles for tenors require a darker timbre and fewer high notes. In the leggero repertoire, the highest note is F5 (Arturo in “Credeasi, misera” from Bellini’s I puritani), therefore, very few tenors can, given the raising of concert pitch since its composition, have this role in their repertoire without transposition.
