Music

Further doing BA in music, you can pursue Masters in music, and if you want to be a playback singer, for that you need to struggle in industry. Other than that, you don't have any way to become a playback singer.

Hello Avanti,
I can understand your situation. Since you are already in 12th and studying science, I would suggest you to first focus on studies and clear your 12th. Once you clear it, start searching for some good western music academies and earn a certification. It needs a lot of focus and efforts. Don't be in hurry as you have enough time to learn a lot. Give yourself enough training through part time trainer in your location or wherever possible. Don't leave your studies in mid.

I would suggest you to first complete your studies, and side by side you can join some class for singing. You can further go for a Bachelor's degree in music. Bachelor's programs typically contain courses in music theory, music history, performance, conducting and composition. A college degree is not often mandatory to become a professional recording artist, but can provide helpful instruction in the form of music courses and one-on-one guidance. You might also consider enrolling in a programme at a music conservatory or completing private lessons with an established musician.

The college offers BA in Classical Music which is a 3-years programme.
