If you are a singer, and planning to take up a course in college bachelor of arts in linguistics and literature is it okay?
First, are you going to want to pursue your singing professionally? If so, a music degree should be your priority. If you want a second major or a minor, take something that interests you. Linguistics or Literature either one would work.
I took a double major in Art and English, and a minor in Education. I studied linguistics and literature both as part of my English degree. You might contact the college or university you are interested in attending to see what is offered.
