Hi Suman,
There is a huge gap in your education unfortunately. But, don't get disheartened, because if you have passion for music, I would suggest you to go for a correspondence course in music from a Sangeet Sameeti Allahabad or Pracheen Kala Kendra, Chandigarh or Gandharva Mahavidyalaya.

Same criterion is applicable for all candidates . 45% or more in aggregate marks including music as one of the subject in 10+2 .

Yes, you can get a degree if you have taken admission in this course through a recognized college.
But it is always advisable to go for a regular degree and attend classes in order to have a good understanding about the course.
