The Scales Aren't Just a Fish Thing Series of Study Manuals gives the student every clue and crutch they need to practice correctly, not requiring remedial correction at the next lesson. Is it an up bow or a down bow...it's all notated. What string is it played on?...the stem color tells the string on which it is played. Is it a sharp or a flat? The circle around the note reminds the student that the note is moving toward another note. The color of the circle gives that clue. It's amazing. Even a small child can learn and memorize difficult pieces correctly.
