Hello everyone. I'm curious to hear from you all what your process is for establishing distinct musical "worlds" within a single soundtrack while still maintaining a coherent overall sound? I've been thinking about this a lot recently since I'm working on the score to a Civilization inspired strategy game that's going to include a lot of different cultures and span a lot of time periods. One way I'm tackling this is by making certain instruments unique to certain cultural categories but I'm also trying to work certain recurring motifs in that connect all of the cultures across time and geographical space.
What are your go-to methods for marking distinct worlds musically? Doesn't have to be strategy related (that's just my experience). I'm curious about other kinds of games too like platformers and RPGs with different level and location music.
Anyway, curious to hear your thoughts on this!
