i am interested in music?which subject i want to take? please guide my career

Hi, Mahadeva. There are many different fields within music: performing, composing, teaching, etc. Do you know which field you are interested in? I can tell you that music is based on mathematical relationships so a basic knowledge of math is essential.

It depends on which direction you want to go with a career in music. Do you like writing songs? Maybe composing is best for you. Do you like playing for a band or orchestra? Maybe you should be a full time musician. It all depends on your skill level and dedication.
