Music Theory

About this work, we read from Faramarz Payvar:

"The book is, in fact, an excerpt from the essential content of music that is exclusively for those who spend most of their time playing and performing music, and maybe due to studying or other matters of opportunity do not have enough time to study sheets related to music. In other words, this book is for musicians who learn music from the note, and also tend to know the origin of it, and to some extent become familiar with the signs and specifications related to it, which is not so illiterate in this field.
