This is the best book for every piano teacher, pedagogue, pianist, parents and piano students of all ages.    I promise you will never regret purchasing it. It is my number one go to book if I have any questions on how to help my piano students improve their technique and piano playing. As a piano teacher this is exactly what I need. Something I can show my students straight away because there are clear instructions for teachers, demonstration videos and colourful illustrations with vivid digital images. My students love it when I show them the illustrations. Worth every penny. Honestly this is one of the best investments for my piano studio.
