Although the format of this edition is little more than a bright new cover on a somewhat cleaned-up version of the old photocopy/facsimile of Green's original typesetting, the content is, as it always has been, pure gold for a string orchestra teacher. The first part of the book, as Green states "is fit for ... college level teaching of this subject", but the last chapter also deals with helping the teacher of younger students to distill the information in the earlier part of the book into material suitable for the middle school age student.
