There might well be that the book for some is good. For Hardline Touch illiteracy is this miracle book, as it was offered by Peter Autschbach in a course, but also nothing. Too sparse, too few explanations on what it is. Again a variety of music books, which ignores the bulk of eager learners, but never reached the music classes at school people. Music teachers do not seem to manage to reach the bridge for most of the population that is interested in learning an instrument and theory. Pity! Will it get rid of the Books, for people who have such a kind of didactics access.
