BBB/BBC. You must have Music Theory Grade 5, Music AS- or A-level, Music Technology AS- or A-level, or be able to demonstrate that you have music-reading skills by taking a brief test. We normally expect three A-levels. One (but only one) of these grades may be achieved from the average of two AS-level grades, one of which should have been taken in year 13, with each contributory grade being in a different subject.
