The purpose of publishing this book is to progressively present the various elements of music art in an educational way, which will help students of music schools and school students to achieve a result that will allow them to read various musical texts, vocal and instrumental, with relative ease. Theory alone cannot offer anything, only when it is applied to the various properties of sounds that derive from their comparison. This application constitutes the so-called melodic exercises (Solfeges). Therefore, it is necessary to develop a familiarity with the sounds from the very beginning. In this book, I will avoid any development of sound production based on pulsating movements. This is purely a matter of natural science (acoustics) as well as the relationship between them from a spatial perspective, which stems from the difference in pulsating movements of two sounds, which concerns mathematics. I consider all these to have been proven. Otherwise, it would be pointless and would deviate from the purpose of this book, which is addressed to young students or older ones who do not have the corresponding knowledge of physics and mathematics. Later, anyone interested can refer to various sources that will provide them with detailed explanations and proof of these matters.

I want to believe that this book, in the way it is offered, will significantly help anyone who wishes to open the huge gate and enter this magnificent structure of high, ethereal, and sacred art.
