What To Expect
A cappella auditions at Harvard take place the week after shopping week, during which most a cappella groups on campus will hold auditions. The process is as follows:
  • A preliminary audition in which you sing scales, do some pitch-matching, and sing a verse and a chorus of a song of your choice for the group (about ten minutes).
  • A first-round callback in which we teach you two of our "blocks" - the music we sing behind the soloist. You'll get to sing with the group to test for blend and learning ability.
  • A second-round callback in which you learn another block and sing a solo from a song the group performs.
  • A Final Night, in which you learn more about the group, learn one of our very favorite blocks, and perform a full-length solo of your choice for the group.

Why Callbacks?
Performance. We perform our own original arrangements twice a year in the historic Sanders Theatre, as well as on an international stage. In addition to our Sanders performances, we also sing at various gigs throughout the semester, from bar mitzvahs to weddings to radio advertisements. Over the years we've prided ourselves on our re-interpretations of modern tunes and our soul classics.
Recording. During your time in the Callbacks, you will be featured on a CD of professional recording quality. Our latest release was Rhythm in Blue, which you can find on both Spotify and iTunes.
Tour. Every year, we embark on two tours, to both New York City and Puerto Rico. You will have the chance to perform in front of a number of audiences on an international stage (plus, spending part of winter break in sunny Puerto Rico is always a bonus.)
Family. Once a Callback, always a Callback. You will be joining a group of people who all love to sing, laugh, and have fun together. Your Callback friends are some of your most loyal friends, and always will be, both during and after college.
