The player on the viola da gamba, shown in the engraving, is a reduced copy of an illustration in “The Division Violist,” London, 1659. It shows exactly how the frets were regulated, and how the bow was held. The most popular instruments played with a bow, at that time, were the treble-viol, the tenor-viol, and the bass-viol. It was usual for viol players to have “a chest of viols,” a case containing four or more viols, of different sizes. Thus, Thomas Mace in his directions for the use of the viol, “Musick’s Monument” 1676, remarks, “Your best provision, and most complete, will be a good chest of viols, six in number, viz., two basses, two tenors, and two trebles, all truly and proportionably suited.” The violist, to be properly furnished with his requirements, had therefore 119to supply himself with a larger stock of instruments than the violinist of the present day.
