THEORY is the theory workbook portion of the Bastien Piano Basics course. Each book contains written work and some short pieces to reinforce the concepts presented in Piano. Games, puzzles, and colorful illustrations make learning fun! Your students will gain a better understanding of the music they are playing, and they will learn more easily when theory instruction is a regular part of their piano studies. Each page is carefully correlated with Piano, Performance, and Technic. Level 2 provides theory materials correlated with Piano.
