I agree with Wumpus, and with av8rmike on this one. Comparing Shore’s LOTR scores (or any of Shore’s music, really) with Williams’ work is comparing apples and oranges.
Williams is the undisputed master of the “catchy” score. He has indeed composed many themes, from Star Wars to Jurassic Park, which are easily remembered once the film is over. His scores are also notable (to me) as being fairly shallow, and they usualy don’t stand up well to listening to them by themselves. There are exceptions, of course, but those exceptions are when Williams steps outside the bounds he usually sets for himself.
Williams’ score for Born on the Fourth of July for example, does not rely on a catchy theme to convey its feeling… it is one of his best scores, in my opinion, because it is one of his most effective. His music for Presumed Innocent is another standout score, a surprsingly simple and understated piece which really enhances the film, and is also quite good all by itself. And though I thought that Williams had really lost his touch recently, with lackluster scores for the Harry Potter movies and flat-out bad ones for the two most recent Star Wars films, he surprised me with a wonderfully fun score for Spielberg’s Catch Me If You Can. Again, for this one, he didn’t go for a catchy theme so much as an overall lighthearted tone to the music. He also got away from the standard “big orchestra” sound of his work and opted for a smaller, more intimate tone.
Which is all to say that Williams has done some great catchy themes, and a few truly great pieces of music… the two typically do not overlap.
Howard Shore, on the other hand, is a skilled composer as well, but in a totally different vein. Anyone familiar with his past work knows that he favors atonal, chaotic scores, often incorporating ambient sound unexpectedly. His music for Silence of the Lambs is a great example for this, as is the music for Seven. If you have, or can get, the Special Edition DVD for Seven, I highly recommend listening to the “Sound and Music” commentary track, which features Shore (among others) talking about how he composes for a film. It’s a very insightful look into how he works, and you can see how some of his methods have worked for the LOTR music.
When I first heard that Shore was the composer for LOTR, I wasn’t sure what to think… I only knew his work from the more understated music I’d heard for Silence of the Lambs or Seven or others, and I wasn’t sure how he would handle the big epic nature of the LOTR stories. Having seen the first two films, and listened to the soundtracks for them often, I can only say how pleased I am. He has proven himself more than capable of expressing the themes of the story on a large, almost operatic scale, and has really outdone himself for these movies. His music has been consistently good so far, and more importantly, it has been consistent to the themes and ideas and feelings of the story. He has also made soem very memorable themes (the “Fellowship” theme being perhaps most memorable to me), but he has not let them take over the whole score, which works very well for the story.
Personally, I’m glad that Shore was selected for the LOTR scores, and not someone like Williams. Williams would have overdone it, and as important as music is to a film (to me, anyway), it would have ruined the whole experience.
