"For me this class is priceless. And when Mr. Andersen closed it with his singing it brought tears and joy for me. Even though we are living in almost the opposite side of the world somehow I feel connected through his song."

"I was in David's class years ago in a Chicago PTG convention. The way he tuned that Steinway is still in my mind. I’ve been a fan ever since. It is absolutely true what he says about "whole body experience.” I have been trying to follow his advice and I feel better because of it after working/tuning customers pianos. I'm a musician (classically trained) and when performing, I'm performing for my self—same thing with pianos. That approach makes me feel good."

"I think of all the possible topics available to us as technicians, aural tuning might be the best suited to this type of presentation (online), for one particular reason: It is fatiguing for me, mentally, to stay focused on and attentive to someone else's tuning work for a long time span. The fact that I can return to this presentation over and over (having purchased the "deep learner" package) will allow me to listen with a fresh ear and clear mind, and get the most out of David's lecture."
