No practicing today; it is just too cold without a heater. So I guess getting one is the goal for tomorrow. Not that I need to spend time studying or anything.

I'm also having problems with dominant 7ths. We were analyzing a song in theory and one of the markings was D7. Everyone seemed to know that's a G chord. wtf. It's clearly marked as a D. I asked for clarification and am still completely confused. And a C7 is actually an F chord? Because it's a dominant 7th it's automatically a V (dominant) chord? If that's so, is there an even more confusing way it could be written? And why did some people automatically know this?
