Made up of members of the GT-level MRHS chorus members (Madrigals, Concert & Vocal Ensemble), this group is one of the largest mixed choruses in the country, working together to perfect some of the most challenging choral pieces available to such large groups. Since its founding in 2005, the Mustang Chorale has been ranked Superior in local and regional adjudications, and has consistently placed at the top in Spring Trip competitions in places such as Virginia Beach, Tennessee, South Carolina, and Florida. This mixed choir has led the state in the largest number of students accepted into the
Maryland All-State Choirs from one school since 2009.
