Just wanted to pop on to share a YouTube resource that I found to be very informative and interesting. It's the following:https://www.youtube.com/user/MusicTheoryForGuitar
The guy does a fantastic job of explaining chordal concepts and helping you to get these into your mind and under your fingers.
It's the best explanation I've come across of many musical concepts and I felt that this guy deserves to be shared - and I'm sure many of you guitar players will get something out of this.
No connection at all with the site (I don't even know or see what the guys name is) - but really very good indeed.
