Dan Lefler here... I'm the director here at DANMAN's as well as a Library Student. I use this Library daily to teach myself how to play my instruments. I guess you could say I was the first Library student. I've increased the songs I can play by the hundreds and I've learned how to play by ear and learn virtually any song I want now by using this Library. Watching the different music teachers and seeing their own unique methods at work has been an amazing tool for me. This Library does what it says... it will teach you how to play music. I personally guarantee it. Check out my Locker stats as a student. And you can call and talk to me if you want to get further questions answered. Or just take the opportunity and start learning today. You will be amazed at how easy it is.
