A boys´ choir is a one made up of boys who have yet to begin (or are just in the early stages of) puberty and so retain their high-pitched childhood voice. Members are known as trebles ("boy sopranos") or meanes ("boy altos"), depending on their range. Boys´ choirs of churches or cathedrals on both sides of the Atlantic may sing alongside and train with men, who provide the tenor and bass parts, in a tradition that dates back traceably to the 7th century, in the case of York Minster, and probably much further.
