I am a trained Indian Carnatic style violin player. Can I play Western songs on a violin with carnatic fingering techniques or do I need to re-learn everything to adopt to the Western style?
If you already play a very difficult music style, I think to pass to western music will be easier for you. The only difficulty will be to adapt to this other system with different "rules".
