Good music to put to a museum tour?

[Ice~Cream+Cake]

Alright so I video taped about 10 minutes of a museum which I am going to turn into a youtube video. The problem is, I don't know what kind of music to set it to. Most of the video is in an African and North American Wildlife Exhibit, and the other part is in the hall of architecture, which is just Roman and Greek structures. Do you think you might be familiar with a song that sounds like it might fit? If so, could you please give me a link? Thanx
