Cool. Makes sense to me to a point. It is important for all guitar players to know Maj and minor pents, maj, hm, mm and symmetrical scales. Pretty much all one needs to know in terms of scales to get PAID. Understanding harmony in terms of theory is equally important to getting reasonalbly PAID.

To imagine for a moment, to make-it, is setting oneself for heartbroke and depression. Music is a cutthroat business. It is the only art form in our society that allows outright stealing and outright plagarism, legally. If you can't read or write or count to at least, seven, you're in deep trouble in just playing. Let's not count, being a lawyer, an accountant, a tax accountant, production engineer, recording engineer, and all the other asundry professions one musician has to know and understand, just to simply stay afloat. After all of that, forget musicianship. Doing it for love, is a pile of crap.

If you want to be a guitar player, educate yourself in a profession where you can beat theivery and dishonesty. Every major star has an entourage and business folk, HE or SHE has to pay for. No other profession, but musicians have this problem. If you don't believe this, just watch a commercial on normal TV. Thirty year old songs are being used, because it's cheaper than hiring a musician to write something original. Another working musician becomes unemployed.
Work as hard as you like in music, but as my father said, find a REAL job. No one will buy the esoteric crap. Lemmings.
