I have fond memories of my stay in Dehradun. I used to stay at Rajpur Road. Part of the magic of staying at Dehradun is that we used to visit Mussorie every two months. To come to your question about Carnatic Music, I think you should try the Centre at 15 Rajpur Road, Dehradun. Please do make enquiries before you send your child there for learning music. All the best for your child.
