The primary goal of the Chorale is to provide all boys in the Upper School, whether experienced or inexperienced, with a substantive choral experience. There is no test for admission, but a short audition is necessary to determine voice part and reading ability. The Chorale rehearses and performs a wide range of music, from sacred classical to world music to folk songs to show tunes. A side benefit of singing in the Chorale is social interaction with Upper School girls from NCS. Occasional casual dinners, pool parties, ice skating, and other events supplement the regular coed rehearsals.
The Chorale sings two full length concerts in the Washington National Cathedral each school year, in addition to the Festival of Lessons and Carols, Commencement for both schools, and local and national choral festivals. Members of the Chorale can choose to participate in an annual spring tour; destinations have included cities from coast to coast in the United States and, internationally, Australia and South Africa.
Rehearsals for the Chorale occur three times every seven-day cycle during the desginated ensemble period, with dress rehearsals before each major performance.
