A boys' choir is a musical group composed primarily of young male singers, typically ranging in age from around 7 to 14 years old. These choirs often perform a variety of music, including classical, religious, and contemporary pieces. The unique vocal quality of boys' voices, especially before they undergo voice changes, allows for a distinct sound that is highly valued in choral music. Boys' choirs are often associated with religious institutions, such as churches or cathedrals, where they perform during services and special events. Many famous boys' choirs, like the Vienna Boys' Choir, have gained international recognition for their performances and recordings, showcasing the talent and dedication of their young members.
