This is my opinion, so take what I say with a pinch of salt. Every nation on this planet has a way of expressing how they feel via music. In the West some prefer Blues. In India, I believe Carnatic music is a form of Blues, though using different scales, combined with exotic trilling…
What our ears get used to is no different to what our palate gets used as we grow up. I remember listening to the Raga’s, since I was 4. However, I had no appreciation of the exotic music at the time. Now many years on, I could happily listen to a sitar raga and not be overly disturbed by it.
I believe Raga’s are another form of Carnatic music, though instrumental and in my opinion an Indian version of blues.
