A Cappella is an auditioned ensemble open to all students enrolled grades 10-12 who elicit a mature vocal tone. Students should have successfully participated for at least one year in the choral program and complete a rigorous audition process. This ensemble provides an intensive and highly rewarding musical experience. In depth study of music from each time period of musical history is explored, including multi-cultural selections from around the world. Vocal production, independence, and musical precision are explored in detail with deliberate emphasis on unaccompanied singing.

They also perform an annual Renaissance Feaste, frequently record CD's and tour biennially.
