I started a music theory blog and I want your feedback as to what concepts/techniques I should cover:
Note Theory
Right now there are two lessons online; 
Circle of Fifths Demystified and the 
D-A-F Roadmap (being able to play 3 different positions of any major chord)
Leave me a comment on the blog if you find it useful or if you have ideas for future posts.  Thanks,
