The intention of this book is to illustrate where the fingers of the left hand are placed on the fingerboard of the violin. The diagrams showing the relative positions of the fingers in each key are complemented by music notation. No attempt is made to show the exact positions of the fingers on the fingerboard, since this depends on several factors. What is shown is where two fingers are either close together, as for a semi-tone, or further apart, as for a tone. The first four positions are illustrated for all keys. Those patterns can then be repeated for the higher positions.
