What an absolutely excellent web site too, they did an incredible job of making some fairly advanced topics seem very simple. To me that's what separates amazing teachers from good teachers. I'm extremely impressed with Chordspace.

Their explanation of secondary dominants is the best I've ever read:

In fact that little theory section they have there, which you can read in mere minutes, is the finest I've ever seen. Totally concise. Chordspace is definitely in the top 10 all time best music learning sites I've ever visited. Great site design, great info, great software...
