From what media is this sound clip from?

I don't remember it in those, though I'm not promising it's not there. I just think it's a clip that has been used many times for dreamy reveals

It’s definitely giving me Disney movie main character enters The Inspiring Area^TM^ for the first time. Or any children’s action/adventure movie. It’s giving whimsy + nature/magic or whimsy + futuristic/factory or campy ceremony (Graduation? Wedding?)
