Description MASTER YOUR THEORY GRADE 2 Master Your Theory is a series of books each of which is an instruction book and workbook combined. It follows a comprehensive course which is planned so that the student may begin with the very first principles of music theory and work gradually upwards through the grades. The course is designed to be useful equally to examination students, AMEB and otherwise, and to those who wish to become better musicians as they learn more about how music is organised and written.
