Apologies to the mods if something like this already exists. As I watch the back and forth between those of us that like to analyze Williams' techniques, chord progressions, etc., and those who want to enjoy his music for how it sounds and not ruin it with a lot of overanalyzing, it occurred to me it might be helpful to have a thread where we do precisely that kind of overanalyzing, and those who prefer not to do so can avoid it. I'll start with this. Recently someone mentioned JW's use of the major triad with diminished 6th for a "spacey" sound (as used at the end of the Star Wars overture, for instance). I've since observed how often this is used (also by Horner in the Star Trek scores). Another observation is that made by others that the Imperial March combination (tonic minor, diminished sixth minor) is also frequently used (i.e. the "evil" theme in ET). What other favorite chords or progressions have you observed?
