[ Classical ] Open Question : Looking for chorale, classical or score pieces that would work well with my video project?

it's a project for a media contest, and it's a video of "new beginnings" (sunrises, flowers blooming, birds taking flight, artsy stuff like that) i need some good music suggestions to go along with it. doesn't matter how long it is, but it needs to match the mood of the video. any suggestions you have would be greatly appreciated thanks!!
