In the midst of all the promotion, discussion, and excitement surrounding the premiere of
Star Wars Episode VII: The Force Awakens in December 2015, there were several excellent essays/posts/comments on music and sound, in this film and in the series overall.
Frank Lehman analyzes the three (!) official trailers for the film:
Musicology Now post. In addition to discussing themes and keys, he makes the general point that "In each preview, Williams’s recognizable melodies are offered as a kind of nostalgizing payoff, something awarded to the listener after a span of thematically ambiguous material."
Lehman also wrote a Mashable column called "7 Things we learned about
Star Wars: The Force Awakens from its music." We won't tell you what those 7 things are, but they're almost all musical hints about individual characters. (Many others have speculated on different aspects of the themes and their presentation, especially Rey's.)
A relative newcomer that we can recommend to students and instructors is
Film Music Notes, written and maintained by Mark Richards, a composer and music theorist (Toronto; Florida State University). He has a six-part series of posts on the new film.
And, of course,
Stars Wars series composer John Williams has several interviews about
The Force Awakens, a film that he says brought new energy and vitality to his writing. Here is one in the
Los Angeles Times. And another on the BMI site:
interview. And here are a couple youtube videos:
