Carnatic Orchestra
The Carnatic Orchestra spreads the light and essence of Carnatic music, throughout college and enlightens the students on the significance of Carnatic music. It also awakens the hidden musical talents of students and bridges the gap by strengthening the bonds between senior and novice instrumentalists. The Carnatic Orchestra conducts practices efficiently, for both usual and special occasions and organizes stage orchestral performances at cultural events organized by other societies and schools.Latest Project
