Kubrick played his own tricks to dissociate the viewer from the onscreen violence. For example, the way the gang fight is set to classical music, in an abandoned theater, with cartoonish violence. And that fight is preceded by a gang rape staged like a ballet. It's the same technique in a different medium.

I'm not entirely sure that those were all Kubrick's tricks though. Classical music is used throughout the book as a way to humanize Alex playing on stereotypes that someone who would've been more refined and upstanding than Alex's character was. While I can't remember what was in the book, it's entirely possible that Alex's narration of the the fight had mentions of music.

I also would argue that Kubrick's tricks weren't all that effective, in that they didn't really humanize Alex or pull the viewer into Alex's perspective, but rather just made the film into more of spectacle.

A lot of the visual elements of the movie struck me as very cartoonish in a way that wasn't conveyed at all in the book. The book is not all that descriptive of aesthetics and visuals in terms of fashion and architecture/decorations. I feel like those are some areas where Kubrick took the most liberties (because there wasn't as much to go off of) and I just found it distracting.
