The Calle Mayor Middle School Choir has about 70 members. The members are 6th, 7th, and 8th graders. The choir fills up early each school year so incoming students need to notify Mr. Nail of their intent to join in May or June of the previous school year.  Choir members who are proficient piano players accompany the group. Each year the choir performs at the CMMS Fall and Winter Concerts, and two judged festivals. In the Spring, the choir puts on a musical production with costumes, lighting and music. The Calle Mayor Middle School Choir is a fun and active group that performs challenging and interesting music, and receives high scores at festivals..
