内容简介：
The theory of music is the "grammar of the musical language." Without knowledge of this language and its grammar, it would be impossible to read music or communicate with other musicians. It would also be impossible to appreciate music itself as a science and art, at a much deeper level. In this self-explanatory book, the music lover will find the proper nomenclature for each theoretical element, the correct notation for these elements, and the rules that govern them. Emphasis is given to several helpful exercises for sight-reading and singing as well as for rhythm sight-reading. The subjects covered are the essentials of the theory of music. The teaching system in this book presents a fresh approach to the materials, and will remain a valuable companion and lasting source of reference.
