I found this video to be really fun to watch. Ever since taking graduate level music theory, in which we studied "alternative" ways to analyze music, I've been particularly interested in texture, density, contour, etc. I even did a couple of projects that involved charting and graphing certain excerpts of pieces, to better depict the contour of phrases. It's probably quite nerdy, but it's something that fascinates me.
What did you think of the video? Cool? Or too nerdy for your liking? Would you like to see similar posts in the future?
By the way, the more info and a color key here.
P.S. I played the 5th symphony in undergrad, and hearing it again made me realize how much I miss playing in an orchestra... :(
