sixteen undergraduate and graduate students (though its size varies). It is one of seven a cappella groups at the school, and is known across campus for its frequent free performances and its funny, edgy interludes used to keep audiences amused between songs. Nationally, Resonance is perhaps best known for its recognition through CASA, the Contemporary A Cappella Society, having received a 2004 and 2008 Contemporary A Cappella Recording Award (CARA) nomination for Best Mixed Collegiate Arrangement, a 2008 CARA award for Best Scholastic Original, as well as a berth on the 2006 Best of College A Cappella compilation CD. The group is also known for regularly hosting the International Championship of College A Cappella New England Semifinals. The group has produced three albums, its latest being the self-titled "Resonance" released in fall 2007. Resonance was envisioned by Sara Jo Elice who, with her friend (and eventual co-founder) Jessica Hinel, fleshed out the original idea while waiting to audition for an MIT Musical Theatre Guild production. Jay Humphries was auditioning for the same production and ended up becoming an inaugural Resonance member as well. In 2001, the MIT Association of Student Activities recognized Resonance as its seventh a cappella group on campus at the time. The name Resonance follows an established joke among MIT a cappella groups of using a science or math-based pun to name the group. In science, resonance has to do with vibration and harmony. Specifically, resonant frequencies are the frequencies that cause natural amplification of signal – a commonly cited example being the singer who can, at the right frequency, break glass with their voice. Keeping with the theme, the resonance name is often formatted as "res(((o)))nance." and displayed alongside a logo of a shattered wine glass. Resonance regularly performs on the MIT campus, at the minimum presenting a single full-length concert per term. Each concert is primarily composed of a collection of songs, both covers and originals, selected and arranged for a cappella by members of the group. Over 100 different songs have been performed by the group since 2001. Resonance, like many a cappella groups, has a single "alum" song, taught to all members and used to close almost all performances. Group alumni are invited to join the current members on stage to finish the night. Resonance's alum song is "Easy People" by the Nields. Resonance has released three albums: Resonance (2007) Left On Red
