Hii Pragati!

The admission process for ba music depends on the College you are interested to take admissions in. Some colleges provide admissions on the basis of the merit list ( class 12th marks ) and some conduct entrance exams. You may visit the official website of the respective colleges and check the process. The eligibility criteria as usual is, minimum 50% marks in 10+2 from a recognised board for general category and 5% relaxation for reserved categories. It's a 3 year semester based course. Some of the college's across India, providing the course are -

* Agra college, Agra

Etc., Hope this helps.
