Caltech Glee Club is a 60-voice mixed choir comprised of undergraduate and graduate students, faculty, postdocs, staff, alumni and JPL employees. Glee Club rehearses twice per week (three hours total) singing art music in a variety of musical styles and languages, from Medieval times to the 21st century. The choir performs for Institute events throughout the year and presents formal concerts at the ends of the fall and spring terms. Each winter the Caltech Glee Club appears as a founding member of the Pacific Southwest Intercollegiate Choral Association Festival. Glee Club often collaborates with the Caltech Orchestra, presenting large choral-orchestral works such as Mozart Requiem, Haydn "Lord Nelson" Mass and "Paukenmesse," Orff Carmina Burana, Vaughan Williams Dona nobis pacem, and Britten Chichester Psalms.
Caltech Chamber Singers is a smaller group selected by audition from the ranks of the Glee Club. This group rehearses an additional hour on Wednesdays, performing advanced music composed for smaller forces. Standard repertoire for this select group includes madrigals, chansons, motets, carols and part songs from the Renaissance through contemporary times. Chamber Singers auditions will be held at the same time as Glee Club auditions and will include a sight reading component. Undergrad and grad students who are accepted may enroll for credit (PA 37).
