I've taught guitar for 45+ years. I'm totally into teaching because to me it's about learning how to learn.
My favorite advice: Best way move ahead on guitar: learn the blues. Leads to jamming, chord knowledge, knowing licks, timing , RHYTHM GUITAR .... Mastering the blues involves getting total flexibility within the form; The Blues is a total Universe within itself; also it can prepare you for developing that flexibility within all kinds of forms and styles.
I believe it was the Blues that really turned me into the guitarist/musician that I am right now.
Right now this channel will have Blues instructionals , my pieces, instructionals on Theory and a whole boatload of guitar styles.
