John Thompson's Piano Series: Theory Drill Games Book Three - Essential Piano Exercises for Beginners and Intermediate Players at Home or Studio

Teaching piano for almost 30 years. John Thompson books are best across the board. The John Thompson “easiest piano course” with the little monsters on it I use for my students no matter what the age; even adults, because the progression and teaching content is superb. When you get to books 5 & 6 it just gets better and better. These books are all top notch. After the 3rd John Thompson theory, I move to Keith smell book 3-10. It’s a perfect progression, and he delves into more advanced theory for the more advanced student.
