Well done.
The theory lessons are spot-on: I think it could have spent a little more time on basic chord construction before leaping into modes, where it starts getting tricky very fast, but maybe that’s just my own weaknesses speaking. At any rate, for less than a latte at Starbucks, I got some tight lessons that gave me the basic vocabulary to get more help from other musicians as well as make sense of music theory articles on Wikipedia. Certainly less than a course at a community college, to say nothing of private lessons.
