1so adjusted, that the strings, in approaching the bridge, may be separated but little farther from each other; otherwise, in tuning, they will be liable to draw the bridge forwards. The tail-piece should be two inches distant from the bridge, and it will be best secured to the button by a loop of E string, doubled and twisted.*
3* The late celebrated L. Spohr invented a very peculiar tail-piece, by means of which the portions of the strings lying between it and the bridge could be so regulated as to produce certain intervals; which might tend, perhaps, to modify little inequalities of tone in some instruments, or prove advantageous in other respects. The figures 5 to 10 will serve to give the reader a clear idea of this contrivance; Figs. 5, 9, and 10 being drawn half the size, and the other three the full size of the tail-piece.
5Fig. 5, consisting of a fore-part A and a hind-part B, is formed of a single piece of wood. The fore-part is perfectly flat at the top, but is worked out underneath, to the extent and in the manner shown in the section of the tail-piece, Fig. 9, and in the view of the front end of it, Fig. 10. This fore-part has four long openings (as at a, a, a, a, in the figure) placed at a suitable distance from each other, and made to receive the like number of little pegs, formed as in Fig. 7. The hind-part B of Fig. 5, which is semi-circular, stands a little lower than the fore-part A, and has its upper edge rounded off, as shown in Fig. 9. It is chiefly remarkable for four small slits, b, b, b, b (extending from the outside towards the centre), made to receive the knots of the strings, and for a little nut, c, formed of bone or brass, which is let into the middle of the semi-circular part B. There are also two small holes, d, d, through which the gut string is passed which connects the tail-piece with the button. Four other small holes pass obliquely from the upper to the under side of the tail-piece, as shown by the dotted lines, d, Fig. 9.
7Figs. 7 and 8 are front and side views of the little pegs which are placed in the openings, a, a, a, a, of Fig. 5, and press on the strings beneath the fore-part of the tail-piece, as shown in Fig. 9. By moving them to and fro in their respective openings, those portions of the strings between them and the bridge are lengthened or shortened, and thus the different intervals are obtained. These pegs consist of two parts, as in Fig. 6, where a represents the knob, or cap, and b the pin which is firmly glued into a hole in the middle of it, after having been first passed through one of the openings, a,
