Music theory
Level IV choristers must pass a Qualifying Exam in both music theory and sight singing in order to be considered for graduation from the Chorus School. Music theory elements of this exam include construction and identification of all commonly- used scales, intervals, triads, seventh chords, and inversions. It also includes demonstration of a knowledge of cadences, simple forms, and bass clef. Aural Skills elements of this exam include sight singing in 3 to 4 parts, in a major or minor key, with diatonic steps, skips and accidentals. As graduates from the Chorus School are expected to be representatives of a comprehensive choral music education, Level IV choristers are expected to demonstrate the highest level of commitment in the Chorus School through attendance and independent study. They are also expected to comport themselves with dignity and grace through rehearsal and concert situations and to represent the Chorus School throughout the community.
