i did a search on "chris juergensen" and found nothing on this site
so i decided to contribute.
chrisjuergensen.com - Lessons and Articles
this is one of the best sites interms of music theory for the guitar i feel.
most sites give you diagrams and expect you to piece things together.
this site, he gives very descriptive information on scales, modes and chords
and how to use them... plus diagrams
it's useful for beginners, and advanced players who just want to brush up on their theory. who knows, maybe you'll learn something new??
When I browsed his articles on modes I noticed that despite the Lydian mode being the fourth mode and the Mixolydian being the fifth mode(he even says this in his articles), he goes on to say that the Lydian mode can be found by moving a perfect fifth up from the root and the Mixolydian by moving a perfect fourth up. Which more or less flips them around. And this isn't a typo, it's constantly referred to as such throughout his articles(EDIT: Although I have noticed that once or twice they're listed correctly). To me personally this kind of makes me question his knowledge on theory but I'll still look through it all and see if I can pick anything up.
Thanks for the link still.
