Hello While I can understand that a well made course can be of some help to have some rhetorical background in regulation and repair, there is a world between theory and reality. And I simply cant understand how one can learn to tune without somebody teaching him (eventually once in the week/month) The problem in pianos is that when hands on experiment are driven on your customers pianos, the results are bad for the customer, and for the next tech which will come to correct your mistakes. I've seen the program of the Randy Potter course, and have find it very well made, but learning to repair and tune pianos can't be at the beginning something you do by yourself alone. Somebody may be there to show you your errors before things go worse. That is going so often. Not enough to be honest and implicated, All the people I meet who have try to learn by trial and error have loose much time and done too bad work. They only can earn a living because the customer quality standard is almost zero most of time, so if they can have the thing made a bang sound and have a nice piece of furniture in the dining room they are happy. So that is my point of view . Good luck Isaac OLEG >
