These four volumes offer essential keyboard works that guide each student through a wonderful body of classical repertoire to practice and perform. The volumes begin with accessible first classics, and with each successive book, students encounter works of greater technical skill. All works are unsimplified. Students and teachers may use the books as stand-alone music resources or they may purchase a book/CD kit for each volume. The CD includes demonstration performances of each piece by acclaimed pianist, Hsing-ay Hsu, followed by helpful master class discussions and performance tips from Ms. Hsu, Scott McBride Smith and Janet Vogt.
