In this volume, the author discusses the “musical secret” that Paganini said he would bequeath to the world as mentioned in Schottky’s biography of the great violinist. The author likens the principles set forth in this volume to the same kind of regimen that Paganini would have had to follow to attain the heights to which he rose. The use of the principles and practice recommended herein should develop the violinist’s ease in ascending and descending the whole range of the finger-board with facility and accuracy, commanding all positions with equal ease.
