The main result of fundamental education is a complex of systematized knowledge and technologies, with the help of which a professional musician is able to solve the tasks assigned to him, as well as fully realize his own creative potential. Each student has a need to project their knowledge to the vulture, see schemes, applications, detect patterns, in other words, the guitarist is looking for ways to visualize the vulture, intuitively suspecting the existence of such. To solve these problems, in fact, a training course "Basis" was created, in which the musical theory is maximally adapted to the neck of the six-string guitar. The book is a mandatory textbook for students of Guitar College, it is recommended for teachers of specialized music schools, as well as for each guitarist as a table book.
