✔ 最佳答案
The answer is yes.
However, your chance depends on how you proceed.
1. If possible, take HKDSE Music subject exam. Even you have not enrolled in the subject, it does not prohibit you from taking the exam.
And you should be able to handle without issue, given your background.
2. You must put this major for your first group of choice of JUPAS. Music, unlike other majors, is a "must interview" major as the program must ask you for an audition in order to admit you.
3. Work with the program, your school, and your music teacher. As Music has a special admission procedure, these will help you a lot in your admission.
