Founded in 1980 by Audrey Olson, the Green Bay Boy Choir has grown to include boys in three levels of vocal experience and ability. All choirs are both training and performing units. The music program is based on progressive vocal music instruction and performance readiness. Choir members must be at least seven years old. Admission to the touring choir is by placement auditions. Auditions are held in the spring or by appointment. School music teacher recommendations are welcomed for ages 7-18. Classical music literature forms the foundation for choir instruction. Repertoire includes contemporary, folk, ethnic, sacred, and secular music.
