REQ: Cinematic Composing Modern Harmony

Sometimes we know what we want to say musically but we find some limitations on the language, especially when it comes to harmony.
Writing a 2 minutes theme can be hard sometimes, but we can still manage to accomplish it with effort, trial and error, and a little bit of inspiration.
But when it comes to developing that theme into a 90 minutes movie soundtrack, a symphony, or many hours of music for a video game… creating different moods and articulating multiple emotional shifts... Now, this can get frustrating!
It’s kinda like trying to express something complex, trying to NOT sound repetitive, but still not finding the exact words to say it the right way.
The simple fact is, the more vocabulary we have, the more things we can say. And the richer our language, the more precise we’ll be able to be to express our musical ideas.
