anyone know the name of the jazz type music played when Maggie does some kind of dance before jumping into the water?
I checked out the list of music in the credits and doesn't appear to be any of them. I can see the film had original music composed by Kyle Newmaster but I can't find any score music
I'm bump-ing this for the OP. When I saw this scene, I muttered to myself "yeah, the 21st century teenagers are all into Big Band music".
But I remembered that Maggie and Beth are enrolled in the dance studio, so yes it could be something the dance teacher picked out that all the girls had practiced for the next day's parade.
Big horn section, sounds like what passed for "avant-garde" in the late 1950s. More importantly, it sounds like movie background music, perhaps for a dance scene. My first guess was the Audrey Hepburn "Mad Dance" from "Funny Face", but it didn't match. But it could be something like that from a Gershwin movie - you could check "American in Paris" or the like.
