Incorrect solfeggio

The book is intended for students of a music school, for parents of students who want to help their children master the basics of music theory, as well as for teachers of music schools, showing interest in various areas in modern musical pedagogy.
The main feature of the proposed methodology is that comprehension of the theoretical foundations of music is due to the teaching of children in solfeggio lessons composing melodies, improvisation, and the selection of accompaniment.

The exception is several songs, whose authorship could not be found out, but they have long been played in the lessons of many teachers
