Welcome to Piano Adventures and one of the essential core books - Performance. As the number of books a child reads skyrockets the ability to decipher the language, the "number of pieces played" will skyrocket a piano student's ability to decipher musical notation. This is especially useful if the pieces build on notes and musical patterns closely correlated with the Lesson Book.
The Performance Book offers various pieces with imaginative lyrics, colourful art, and sophisticated teacher duets. Teachers with shorter lesson time may consider assigning the correlating Perfroamcne piece as a "challenge assignment" to learn independently. Much can be observed about at-home practice habits, retention of the lesson material, and learning style. A teacher's congratulations for self-study is a powerful persuaded for students to apply what they know.
