TheraTunes was created by Kaiya and Nirvaan Pandit. The program initially was targeted as an in person teacher training with research-based originally composed songs for intellectually and/or emotionally challenged children. Subsequently, a free app was created, replete with songs, lesson plans and pedagogy, for use by all primary school music teachers as well as therapists. The Theratunes app currently has over 10,000 users and is still growing.
