tonebase is opening doors for me as a piano player and a musician that I thought closed decades ago. Having tonebase is like having on demand access to the entire faculty of the Conservatory, you can't get that at this price anywhere in the world. I find it great that you can find the thing that you need to address in your playing. There's a there's a video and a world class instructor that can walk you through it. And you can hit the rewind button as many times as you need to and go over that lesson over and over again until you get it down. tonebase is wonderful and I'm glad I found it highly recommended to anyone
