This channel is 98% about teaching guitar - mostly Classic Rock of the 1970s and 1980s, but I also teach technique, simple theory, R&B, a little Jazz, Bluegrass, and Country ... and oh yes, lots of Blues!!And I take requests too, although there's no guarantee for me to do it or for the time-frame. However, I *DO* give private lessons and make custom videos, so please inquire if you'd like that obscure song that nobody will do for you on YouTube!The remaining 2% is math. I also *love* math and teaching math. You may not believe this, but there's a very close connection between music and math. And I love to teach both!Have a look at my website if you get a chance: http://www.markzabel.com. Or join my Facebook group or visit me on Teachable!
