Those have words/lyrics. I'm thinking more like silent films except where the music isn't incidental. Symphonies can sometimes have singing, but the singing wouldn't be done by a character on-screen.
There was a scene in Peter Weir's "Fearless" starring Jeff Bridges where a key sequence was silent except for a recording of a Gorecki symphony... beyond that I'm kind of drawing a blank.
EDIT: Ballet would be a better example. Except without so much dancing. :-)
I know you're talking about specifically word-less music but there are some pretty cool examples where the lyrics are more abstract and animation is connected without being literal.
