[Illustration: Fig. 40. VIOL DA GAMBA. (From Reissman's "History of German Music.")] [Illustration: Fig. 41. THE BARYTONE.] It is not easy within present limits to apportion the various steps by which the violin reached its present form. The first eminent master of violins, as distinguished from small viols, was the celebrated Gaspar da Salo, who lived and worked at Brescia during the latter part of the sixteenth century. The model varies, and the sound holes are straight and flat. His violins are small and weak of tone, but his tenors and basses are much sought for. His model was followed some time later by Guarnerius. The real mastership in violin making was attained at Cremona, in Lombardy, where were many religious houses with elaborate services, and a surrounding population of wealth and artistic instinct afforded the mechanic an appreciative public. It was here early in the sixteenth century that we first find the Amati family in the person of the oldest known violin maker, Andrea, from whom Fetis quotes two instruments dated 1546 and 1551. One of them is a rebec with three strings; the other is a small violin. They are a distinct advance over the violins of the western school, but they stop very far short of the modern instrument. The tone of his instruments is clear and silvery, but not very powerful. The most eminent of the Amatis was Nicolo, 1596-1684, a son of Geronimo and grandson of Andrea. The outline is more graceful, the varnish deeper and richer, and the proportions of his instruments better calculated. His instruments have greater power and intensity of tone, and his tenors and 'cellos are very famous. But the Cremona school came to a culmination in the works of the pupil of Nicolo Amati--Antonio Stradivari, 1649-1737. This great master of the violin pursued the principles of the Amati construction down to about 1700, having then been making violins for upwards of thirty-three years. After 1700 he changed his principles of construction somewhat, and developed the grand style distinguishing his later works. He marks the culminating point of the art of violin making. It was he who perfected the model of the violin and its fittings. The bridge in its present form, and the sound holes, are cut exactly as he planned them, and no artist has discovered a possibility of improving them. His main improvements consisted (1) in lowering the height of the model--that is, the arch of the belly; (2) in making the four corner blocks more massive, and in giving greater curvature to the middle ribs; (3) in altering the setting of the sound holes, giving them a decided inclination to each other at the top; (4) in making the scroll more massive and permanent. Every violin of Stradivari was a special study, modified in various details according to the nature of the wood which he happened to have, sometimes a trifle smaller, a trifle thicker in this place or the other, or some other slight change accounted for not by
