Edna Mae Burnam: A Dozen A Day Piano Book One: Primary (Pre-Practice Technical Exercises)
A Dozen A Day Book One: Primary contains pre-practice technical exercises for the Piano. The purpose of this book is to help develop strong hands and flexible fingers.
The aim is to learn two or three exercises at a time, which should be played each day before practising. Only when these are mastered should you add another. When all in the first group are mastered, the next group may be introduced. Many of these exercises may be transposed to different keys.
