When Joachim was asked why he preferred a Stradivari to any other violin, he replied: “A Stradivari is a mine of musical sound into which the player can dig and bring out hidden beauties of tone.” And then he went on to say: “While the violins of Maggini are remarkable for volume of tone and those of Amati for liquidity, none of the celebrated makers exhibit the union of sweetness and power in so pre-eminent a degree as Giuseppe Guarnieri (del Gesù) and Antonio Stradivari. If I am to give expression to my individual feeling, I must pronounce for the latter as my chosen favorite. It is true that in brilliancy and clearness, even in liquidity, Guarneri is not surpassed by him; but what appears to me peculiar to the tone of Stradivari is a more unlimited capacity for expressing the most varied accents of feeling. The tone seems to well forth like a spring and to be capable of infinite modification under the bow. Stradivari’s violins affording a strong resistance to the bow, when resistance is desired, yet responding to its lightest breath, emphatically require that the player’s ear shall patiently listen until it catches the secret of drawing out their tone. Their beauty of tone is not so easily reached as in the violins of many other makers. Their vibrations increase in warmth the more the player, discovering their richness and variety, seeks from the instrument a sympathetic echo of his own emotions: so much so that these violins seem to be living beings and become, as it were, the player’s familiars—as if Stradivari had breathed a soul into them in a manner achieved by no other master. It is this which stamps them as creations of an artistic mind, as positive works of art.” * * * * * We have talked about the construction of the violin and of its great makers; now let us turn our attention to the actual playing of the instrument. The four strings—G, D, A, and E—are made of catgut[8] and the lowest—the G—is wound with silver. These strings do not run exactly parallel but taper gradually from the bridge to the nut. The nut is a tiny, raised bar of ebony at the extreme end of the fingerboard; and on the nut the strings rest on their way to the pegs. Through each peg a tiny hole is bored. The string passes through that hole and is looped around itself; and then the peg is screwed up, or turned, until the proper note, or pitch, is found. The violin is tuned in fifths. These four strings give what are called the open notes—G, D, A, and E. The lowest note possible to get from the violin is this open G.
