Resonance is an a cappella CCA under the NUS Cultural Activities Club, formed by a cappella aficionados who love to sing. First formed in 2000 by members of CACS Voices interested in trying out a cappella music, Resonance hopes to promote interest and knowledge of a cappella music within the collegiate community, while giving its members a chance to experience stage experience first hand. We sing in a variety of languages and genres including pop, doo wop, swing, techno, jazz and classical.
