I'll be doing some editing on the DulciTheory pages over the next few weeks.
DulciTheory was originally an email newsletter, but I moved most of the newsletters to my website, and I've tried to format them a little nicer than the plain-text format of the newsletters.
The whole idea behind DulciTheory was to add some useful applications and expand the scope of my Music Theory and Chord Reference book. The book has been very popular over the years, but it is more like a quick reference than anything else. As I get to going over the theory pages, I will be looking toward improving them and, of course, adding some new articles. So please let me know if you have some ideas for future topics, or if you need help in applying what is already there.
