Boys' choir

A boys' choir is a choir primarily made up of choirboys who have yet to begin puberty or are in the early to middle stages of puberty and so retain their more highly pitched childhood voice type. Members of a boys' choir are technically known as trebles and often termed boy sopranos," although occasionally some boys sing in the alto range. Some boys' choirs of churches or cathedrals are further supported by older male voices singing tenor and bass; these singers are sometimes former choirboys.

Boys' choirs, as a Western World cultural tradition, developed in the Middle Ages. Boys were then responsible for contributing a treble sound to church music, since women were typically barred from the performance of sacred music in a public (gender mixed) context. Some of the oldest existing boys' choirs—such as the Vienna Boys' Choir—trace their roots back to this time.

In 1498, more than half a millennium ago, Emperor Maximilian I moved his court and his court musicians from Innsbruck to Vienna. He gave specific instructions that there were to be six boys among his musicians. For want of a foundation charter, historians have settled on 1498 as the official foundation date of the Vienna Hofmusikkapelle and—in consequence—the Vienna Boys' Choir. Until 1918, the choir sang exclusively for the court, at mass, at private concerts and functions and on state occasions.

Today, church traditions with strong roots in the Middle Ages (in particular, Anglican, Catholic, Orthodox and Lutheran churches) continue to host many boys' choirs. The Anglican church is particularly well known for its contributions to choral works and arrangements for boys' voices. However, the general inclusion of female voices in church music since the mid-1800s has significantly reduced the importance of boys' choirs as church institutions. Many present boys' choirs were either founded or reconstituted during the first half of the 20th century as independent concert choirs. In 1917 an article in The Musical Quarterly identified - and criticized - a trend toward the foundation of many boys' choirs in the USA, which the author derided as the "boy choir fad."
