Vocal music: including Bel Canto and ethnic groups, most schools should prepare two songs, one from China and one from a foreign country (sung in Italian, some schools don't require it, depending on the school).
Accompaniment: refers to piano accompaniment songs, test, choose one or two songs, and draw one on the spot. You may have to test yourself to accompany yourself, such as playing the piano and singing, or accompany others.
Generally speaking, it depends on the annual recruitment announcements of various schools. I hope it works for you. I wish you success in your exam!
