Treble voice A treble voice is a voice which takes the treble part. In the absence of a separate descant part, this is normally the highest-pitched part, and otherwise the second highest. The term is most often used today within the context of choral music in reference to youthful singers. The American Choral Directors Association defines a treble as "a singer, both male and female, ages eight to sixteen".
