Well stated, Tangmo. Again, I'm reading the majority of You Tube guitar teachers as following a certain trend in the musical tastes of the students, the kind of musicians they aspire to be. In our time, blues and rock, closely related, are the forms guitar students want to play. I don't really understand blues soloing, so can only assume these guys know what they are talking about. Blues guitar is not usually associated with traditional melody, more rhythm. I like Rod Stewart. He tends to bridge the gap.
My point is, people who follow the on line teaching ought to know they are being directed to a style. And, true enough, nothing compares with the heart felt feeling of the blues.
