Hi Jade. If your type of scholarship allows you to take any subject, then go for it! I'm not sure what classes you could take about vocal technique where you wouldn't have to sing yourself. But there are SO many resources out there - books, YouTube vocal teachers, teaching CDs (check your local library) - so don't limit yourself to the classroom only. Also, think about why you are fascinated by vocal technique - do you want to teach others about it? As for taking general music courses to learn about music, that is always, always, always a smart choice. I wish you well in all of this. Keep learning, searching, and striving. And don't be too hard on yourself. Be happy!
