The Theory Books of the DAVID CARR GLOVER PIANO LIBRARY are written in programed instruction" style, one of the most effective means of learning in modern education. Programed instruction is based on three generally accepted principles: 1. The material is presented in small steps called "frames." 2. The student makes an immediate written response to each frame so that his learning is constantly checked. 3. The student knows if his answer is correct. The Theory Books are written for the Preparatory Age piano student. However, the fundamentals of music are presented in a logical order making the books useful for any beginner. The Theory books are correlated to the DAVID CARR GLOVER PIANO LIBRARY, but can be used with any course on music of this level of advancement."
