Leopold Mozart's "Violinschule" of 1756. The Frontispiece
he writes of this picture: "... [it] has a rather pleasant and relaxed appearance. Here the violin is quite unconstrained; held chest high, slanting, and in such a fashion that the strokes of the bow are directed more upwards than horizontal. This position is undoubtedly natural and pleasant to the eyes of the onlooker, but somewhat difficult and inconvenient for the player as, during quick movements of the hand in the high position, the violin has no support and must therefore necessarily fall unless by long practice the advantage of being able to hold it between the thumb and the index-finger has been acquired"
