The Texas Girls' Choir is composed of 5 Choir levels. Each girl enters the Preparatory Choir and then each semester has the opportunity to progress to the next Choir level by audition.
All choirs perform and naturally the more advanced choirs perform more often.
Touring girls are selected from the Concert choirs. In addition to improving and developing her voice, the program teaches the girls stage presence and some choreography. There are 4 handbell choirs, each with an increased degree of difficulty. Handbell choir performances are a part of each concert in the annual concert series. Bell choirs rehearse on Saturday mornings before or after regular rehearsals.
