Mirman School offers multifaceted music programs, led and overseen by Director of Music Nicolás Kello, that cater to students’ diverse interests and talents.

In the general music program, which runs from Kindergarten through Upper School 2, students immerse themselves in singing, moving, playing classroom instruments and games while exploring fundamental concepts of music theory and literacy. Through an inquiry method rooted in guiding questions, students investigate the meaning of various songs and music's social/historical context while exploring themes of inclusivity and equity. Musical experiences are carefully sequenced to provide step-by-step development in both skill and understanding and are thoughtfully integrated with other elements of the academic curriculum at each grade level. Children also explore and prepare repertoire for the Winter Program based on overarching themes and cross-cutting concepts.

The vocal music program at Mirman School has two performing and touring groups led by Choir Director Dr. Lauralie Pow: the Mustang Chorus and the award-winning Concert Singers.

Mustang Chorus, Mirman's entry-level choir, is made up of students in Fourth Grade.

Based on space availability, the Concert Singers is offered to Upper School students who meet the requisite vocal skill level and who desire to develop their musical knowledge and vocal ability at a more sophisticated level. Each singer develops a work ethic and an awareness of the responsibilities that promote the highest level of success for the individual student and program as a whole.

Concerts produced throughout the year include the annual Winter Program and the Spring Concert.
