Many of us here in the Bay Area learn Carnatic music. But, we have no understanding of the origin or the methods of the music. There are already lots of books out there. Universities and colleges have published many books on music. If you are keen on learning a lot, there are many books on music that are very much available.
Dedication is the most important thing.
Becoming a Carnatic singer is not easy. Concentration, practice and dedication will only get you there. A sincere guru could tell you if you can master it or not. Once you know, you can do it, then it is only your sincere effort that will take you where you want to go. I always read and refer to musical books.
