In 2001, the School inaugurated a new Music School, with modern and updated spaces and facilities, which dramatically increased the interest in things musical at Doon.

The Music School offers training in vocal, tabla, sitar, sarod, flute, drums,guitar, violin and piano.

Many of these instruments are played by the boys at Assembly every morning.

The addition of western classical and popular music have been enthusiastically received by the students.

In April 2001, 2002 and 2005, the School Choir and Orchestra toured Mumbai, Chennai, Delhi and Dubai. They performed at the Nehru Planetarium and the Academy of Music, Vasant Valley School and The Modern High School.

The money that was raised was given to local charity, social service projects, earthquake relief operations, for Tsunami relief work and refurbishing school facilities.
