Filmmakers communicate via words… words about characters, narrative, subtext, style, pace, intent, concepts and so many things involved in storytelling.

It is challenging for composers, whose native language is music, to communicate about film using words.
PRACTICE MAKES BETTER
A great place to practice articulating about film could be in the COMMENTS section in the 50+ film clips already posted in the YOU’RE WELCOME posts on this Forum.
Each clip is followed with the question:
WHAT ARE YOUR THOUGHTS?
Perhaps imagine being the composer of those scores and discussing them, in filmmaking terms, not musical terms, to the filmmakers.
Or perhaps imaging being in a meeting to have scored those films as they were ultimately done and pitching that approach and why?
IT’S OKAY TO INITIALLY SUCK AT THIS.
I bet your first attempts at learning an instrument or writing music were awkward and clumsy. BRAVO for trying. BRAVO for practicing. BRAVO for putting your early, sloppy efforts at this out into the world.
