Which pronoun in the passage is unclear? Voices in the Choir A choir is usually divided into four groups of singers, depending on their voice ranges. Sopranos and altos sing in the higher ranges. Tenors and basses sing in the lower ranges. Sometimes, a woman will sing tenor if her voice is low enough. Good choir directors will make the best use of their singers' voices. The best choir performance takes place when all of the voices blend together into one voice. Listening to it can be a wonderful experience.
