We Call On Him

Violin "methods" generally pass from the first position to the second, from the second to the third, and so on in numerical order.
To go directly from the first to the third position seems simpler and easier. Later, the pupil will find his second position between the first and the third. Moreover, this manner of proceesing will allow us to begin, at the same time, the highly important study of the shifts. To learn the fingerings of the positions seems, at first, to be the difficult point. Yet this in only a matter of memorizing figures.
Take a pupil who already knows his positions, and give him a fairly rapid slurred passage going from one position to another. The difficulty which he will encounter in playing it will be precisely in the changes of position which we call "shifts".
