If you don’t know her already, let me introduce you to the wonder that is Vi Hart, the world’s leading Recreational Mathemusician. I chose to sit through her logarithm video only partly to refresh my memory of the math foundations behind logarithms, and partly as an excuse to introduce her to anyone who isn’t already one of her six hundred thousand followers or 41 million Youtube visitors.

Answer still pending.) What I found instead was one of Vi Hart’s best videos, explaining 12 tone scales, another bit of music theory I knew nothing about. This video is 30 minutes long, and I defy you to watch it for more than 2 minutes and then try to stop:
Charisma, they name is Vi Hart.
