Greetings everyone!

You see, I found this wonderful tune on this youtube video and I really liked it. Since I enjoy instrumental and classical music, I tried to find the name of the track for 2 days now and ran out of sources.
The tune is on this video: http://www.youtube.com/watch?v=mqxU8etRA04

Thank You very much!
