Tenor

A tenor is a voice category within classical music whose tessitura lies above baritone. It is the highest conventional male voice. The standard tenor repertoire ranges from low C3 to high tenor C, though there is a vast body of work that extends the range in both directions.

Vocal range
In the conventional repertory of opera, the lowest pitch a tenor would typically sing is B♭2. However Rodrigo di Dhu in Rossini's La donna del lago and Rinaldo in Rossini's Armida, for example, both demand a low A♭2. The highest required note in the conventional tenor operatic repertoire is D5, which can be heard in Adolphe Adam's Le postillon de Lonjumeaus "Mes amis, écoutez l'histoire" and Fromental Halévy's La Juives "Loin de son amie." The highest note in the leggero repertoire is F5 (Arturo in Bellini's I puritani's "Credeasi, misera"), yet this pitch is often omitted or the tenor resorts to head voice (or falsetto). The highest written note for a tenor voice is G5, which appears in Mazzoni's Antigono, a rather obscure opera, in the role for the baritenor category. It's crucial to note that these are not the the tenor voice's general boundaries; numerous singers, both classical and contemporary, have gone well beyond these two extremes.
