Chances are good that you’ve already seen, or at least seen a link to, Vi Hart’s astonishing video about twelve-tone music. It has almost a million views, which represents a pretty tiny fraction of the total number of people on Earth, but I suspect the correlation with readers of this blog is high.
But I’m posting it anyway, because there might still be some readers who haven’t watched it yet, and that would be a shame. It’s that good. Now, it is a #longwatch, as they say in Twitter-land — half an hour long! Let’s just say it’s more rewarding than catching the latest episode of Two Broke Girls.
