You don't need to take a vocal exam. But few people recruit dulcimers. If you are a freshman, you can do it. Now you're going to Yin Tian to learn from a dulcimer teacher, and then you'll go to Senior Two and ask the teacher to introduce you to a music theory teacher and a solfeggio teacher to learn music theory and practice your ears. Music theory is very simple. There must be someone who can teach it for half a year. I rented a house next semester in my second year of high school, next to Yin Tian, and suddenly I practiced my major. Finally, if you pass the professional exam, go back to make up the culture class immediately and take the college entrance examination. More than 300 points is enough. This is the only way to enter the Conservatory of Music. I hope it helps you. If there is anything you don't understand, you can ask me.
