There's an old saying that talking about music is like dancing about architecture, and I wonder if the person who first said that — the source is unknown — had ever considered using drawings to "talk" about music.
Take a look at the seven-minute video below and see how illustrations can serve as an introduction to music history. (A little better than dancing about architecture, I'd say.)
I'm amazed at how many styles of music and significant composers the video found time to include. Enjoy!
Note: Since the embedded video from You Tube was disabled, I have provided a link to a site where it can be viewed in its entirety (posted April 4, 2013).
