T331 deals with musical skills in the context of music since 1900. The validation/exemption exam for T331 has two components: an aural exam and a hearing. The pitch materials that students should expect to encounter include intervals (simple and compound); extended tertian, quartal, and quintal sonorities; modal, octatonic, and whole-tone scale patterns; and melodies without a specific tonal center. Rhythmic materials include polyrhythms; non-traditional beat divisions; changing meters; metric modulation; and irregular meters (e.g. 5/4, 7/8). The exam includes melodic and rhythmic dictations as well as error-detection exercises.
The aural exam takes about 60 minutes. Students who pass the aural exam are eligible to take a hearing in order to complete their exemption from T331. The hearing tests the student's sight-singing, reading and conducting of rhythmic patterns at sight, and the ability to realize extended sonorities (like those mentioned above) in four voices at the keyboard on any given bass note.
The T331 course packet summarizes all of the topics above in greater detail and provides examples of exercises one might encounter while taking the course. This packet is available at university bookstores.
