I myself have mentioned these, that I could find now:
In the track "Snowy's Theme," I am absolutely blown away by that short section 1:00-1:10, which has been adapted from the cue "Snowy's Chase": the careful use of the timpani (only 2 hits at the right strategic moments), the masterful interplay between strings and the piano. I must have listened to that alone 10 times already. What that section seems to say is, "Yes, Snowy is cute and slightly clumsy and all that, but when there's real danger, Snowy's more than up to meet the challange!" I just love how JW's music seems to tell entire little stories or anecdotes, even in such brief snippets; he sure does it better than anybody else.
"The Flight to Bagghar" is of my (several) favorite tracks. I know this one I will be listening to over and over again... over the next couple of decades! What I especially like about it: 1. the short bit 1:09-1:12, which I am pretty sure is JW imitating through the orchestra the propellers of the plane stuttering into life (it sounds that way anyway), 2. the rendition of Tintin's theme which follows it (not the most heroic example, but surely the most uplifting), and 3. the frenetic over-the-top strings (2:13-2:19) which is SO reminiscent of ToD somehow and which is then topped a few seconds later by the strings doing: 2:28-2:34. As if JW is saying, "You think that was good? Then listen to this!" I swear to God, when I heard that for the first time, I actually laughed out loud!
But one of my favorite moments has to be the flute solos at the beginning of "Pursuit of the Falcon." At 0:12-0:19 JW masterfully combines light strings with the flute playing rapidly to conjure the image of a bird struggling to gain altitude... you can almost feel the orchstra struggling too! This sends pleasurable chills down my back every time!! This is not just what he did in PoA, you see. This is JW building on that same idea but enhancing it with light strings... All I can say is WOW!!! Well done, Johnny. And the continuation at 0:23-0:29 too, of course.
Other examples by members (that I could find on short notice):
The HP-esque mystery music 2:40-3:00 of Marlinspike Hall
Am I the only one who finds this enchanting and mesmerizing? Is it a particular theme?
It's one of those...I wish he'd developed it further, but alas you only get 20 seconds.
3:08 in The Pursuit of the Falcon
Best moment in the score.
The Pursuit of the Falcon theme [4:17 to 4:36] statement is a lot more epic. Love its grand fashion and it'll probably be a lot more satisfying for those looking for great thematic moments from Williams.
That being said, I love the harpsichord statements of the theme in The Adventures of Tintin [0:34 to 0:38].
Well, what other examples are there? Bring them on!
