Howdy from Jackson Hole!Buy this book. Just do it. Don't be dissuaded from it being "Kindle", as Kindle editions now have app support on other platforms than the proprietary "Kindle" reader.The internet has a plethora of guitar instructors. Many offer instruction that gets you to the grade school level of playing a few chords to a few songs. Erich starts you out in kindergarten, progresses to grade school,junior high & high school. He's dead serious about laying foundations that will make Masters and PhD level playing possible if you choose someday.Erich's into martial arts also. Hence the Ninja outfit on the book cover. His Ninja approach to learning guitar emphasizes dedication, fun, economy, and building from basics. This is ultimately the only way in martial arts OR guitar the seemingly impossible becomes so second nature it's truly effortless.All prospective students should know the extreme power of this Kindle book are links to TONS of YouTube videos he's posted. It's like having a face to face lesson at home (arguably better as he has vastly more experience than the local you'll likely end up with).To Erich (& others)... I'm physically unable to do a lot of this book. I've found my tennis elbow is aggravated by some chording. I'll never strengthen my hands to make a G Major painless. Will I quit guitar? Nope. I'm going to Ninja around my shortcomings, and turn them into strengths. For instance... There's a simple easy alternative to the traditional G Major chord requiring only 1 finger fretting, Hitting that simpler, less beautiful chord with a smile and technique elsewhere will divert attention & work magic (& Erich is also a magician). Dig it? His style and progressive steps will make me the best I can.Are you skeptical? Google search a Rolling Stones stalwart: "Keith Richards fingers pictures". You'll see pictures of his hands proving he has very severe osteoarthritis. Those huge knuckles are nonfunctional at this point. They no longer hurt because they've been welded into place. Yet, Keith invents and performs amazing stuff. My personal physical limitations can't compare to his. I'm going to stick with this method and adapt it to my personal style.Happy Trails! to Erich and all!
