Great question Ben!
So for starters I would be a fool if I did not mention that I have been teaching online courses on music for many years (see above in the top menu “Courses”), or check them here: courses on music composition, production & sound design.
I have also taken the Evenant course:
Cinematic Music – From idea to Finished Recording
This is a very long and extensive course that goes through all the main aspects of writing cinematic music, and I can 100% recommend it.
They have a course on Trailer Music composition too, but I haven’t taken it myself so can’t offer any insights there I’m afraid.
I can also highly recommend checking out some courses from a good friend of mine (also member of this community) Jonathan Armanandy @SoundtrackAcad. He is a very good teacher, and explains everything in a clear way.

Thinkspace I have no experience of at all, but their channel on YouTube is hilarious, and you can but only love that guy running it
