"Music Theory and Practice" is compatible with current international literature and is adapted to the Greek reality. It is intended for students or music enthusiasts without prior theoretical training, who wish to gain productive knowledge of the basic terms, symbols, concepts, and functions of music theory.

It is the methodical and flexible manual for music theory classes in all educational institutions: conservatories, music schools, training institutes, and higher education institutions. The series "Music Theory and Practice" consists of three volumes, with the first volume addressing theory and the second and third containing exercise books.

Chapters 1, 2, and 3 examine the fundamental elements that shape musical sound: notes, rhythm, and expression, while chapters 4, 5, and 6 explore the relationships that develop among musical tones: intervals, scales, and chords. Specific attention is given to the rules of musical notation, classification of musical instruments, and documentation of the scales of Greek traditional music.

The methodology proposed by the author encourages the student to take one step at a time. To start studying from the example and move to understanding the concept from the theoretical text. With the belief that acquired knowledge is reinforced through practice, the two volumes of exercise books contain a wealth of simple applications and creative problems, while activities for aural training and composition are indicated.
