Having real teacher is the ultimate level when it comes to learning but if it is impossible - OpenStudio is the ultimate solution. Initially it was too "advanced" for me because I had zero piano background whatsoever but after one year it got completely accessible to me. I'll be playing decent jazz within 10 years of self-training and that is completely doable for middle aged (I'm into late 40s now) corporate employee. I'm technology lead and IT architect in one of those bigger banks. Considering technicalities - all works as expected, lessons are available without interruptions pretty much always. Even those older materials are very good indeed. Adrian
