My musician friends who are scholars in indian music tell me that there is a difference between a written raaga and a performed raaga and in a performed raaga, the actor has the right to improvize on that.

Im trying very hard to not go into the rabbit hole which might become purely academic :) But i would think that if we take how youtube content is structured, or tiktoks are, each format would lend to a new structure.

Thats my sense, i could be wrong. What do you think?

There are 72 major raagas - called mela kartha raagas - those are the root raagas, and there are combinations and permutations done that generates the janya raagas - which is children raagas (there are thousands of those - and different artists can create variations on these).

Most films in Hollywood have narrative beats - its 7-8 beats. Each tv show for eg, has 5-6 beats. Most micro drama episode has 2-4 beats. Its quite structure that way.

If you take a structure like Save the cat, or Heroes' journey, the order of the beats are also quite well laid out - just that those two structures dont cover the span of stories, and rest is all quite undocumented.

Im trying to work backwards - and quite aware that i am probably identifying derivatives than the root, but even the derivatives can be quite useful to guide others from generating engaging content.

I am not aware of Aarne Thompson's work. I'm looking it up right now...
