Well, I need some help regarding potential music ideas for a movie idea of mine.
Most recently, I was talking about doing a live action/animated movie someday, to be called ToonTalker, or something like that, and it is to be both an epic, Avatar-esque love story involving an animated cartoon human girl and a live action human boy as well as an animated cartoon fantasy-meets-live action reality epic coming-of-age saga.
But it is also to be one about a clash of good versus evil in which both humans and highly-stylized Genndy Tartakovsky/Samurai Jack-esque (and largely 2d hand-drawn) animated cartoons will come into conflict with an evil Aku-like Dark Lord and his terrifying hordes of evil minions—all told through the eyes of two distinct characters (one live action, the other animated) and their respective families, two distinct worlds tethered into each other by some portal (like, for instance, one inside a TV set) that allows free passage between both worlds, and two distinct cultures.
(I am really adamant that the live action family of the live action human boy and his cultural heritage be American, and I am also really adamant that the animated cartoon family of the animated cartoon girl and her cultural heritage be Japanese)
Anyway, I was wondering:
What kinds of appropriate musical instruments should I, or even a potential music composer, employ in order to represent the diverse cultures of my live action human boy character’s live action American family and his animated cartoon love’s animated cartoon Japanese family, respectively?
May I ask why you're so adamant about an American boy falling in love with an animated Japanese girl? To me this a pretty transparent assessment of the white-male fascination with Japanese pop culture. It could work and I don't mean to criticize anything. Just from an objective view.
Have you listened to many Anime or Game soundtracks? I was outlining a story and found some instrumental pieces that worked well as an inspiration.
