It's possible they won't allow me to show you right here on this very board - but it is certainly worthwhile to go to YouTube -and choose the highest resolution your bandwidth allows to watch this!

Please keep that in mind before merging it to that thread, moderators!
I've seen this one before, and a few others uploaded by same YouTube user (there are something like 250 - Beethoven, Bach, etc., plus a TEDx presentation.) Really fun to watch, and gets even better if you've ever done formal and structural analysis of the pieces in question.
^Plenty of the sorts around - I actually wanted to post Beethoven's pastoral here! - most people would recognize this: [YT]http://www.youtube.com/watch?v=h0ZhcOmYwIk[/YT]
