I took music theory but that was some 50+ years ago!

I would suggest looking for a music theory book that is dedicated to your main instrument. I have a couple that pertains to the guitar that has helped me tremendously.

What I like are semitone modulations. Things like Am7, Am7b5, Gmaj7, G13b9 are semitone moves. Many times in a blues song I will replace a dominate 7th or 9th with a 13th.

But rule #1 as Mac has said many times "If it sounds good then it is good"!


I'm no longer allowed to go caroling at the psych hospital.
I guess Do You Hear What I Hear was a bad song choice!
