1Proper vibrations being exceedingly undesirable in the soundboard, they are prevented by gluing thin ribs of wood—the belly bars—under it, of which the grain runs in a different direction to that of the soundboard. These bars give elasticity and help the formation of vibrating centres or nodes. The soundboard has to be tense to take up the vibrations initiated by the strings.
3(5) The bridges (fig. 3) are two in number in the piano, each corresponding to a similar part of the violin, i.e., (1) the belly bridge to the violin bridge, (2) the wrest plank bridge to the nut of the peg box of the violin (see the chapter on the violin). The first of these bridges, by means of which the vibrations of the strings are communicated to the belly is made of hard wood. The belly bridge is divided in all pianos, straight or overstrung. With the latter the divisions are disposed at differing angles, so that the bass bridge strings cross over the others in the lower part of the scaling. As a matter of fact, overstringing has entirely changed pianoforte construction, being in consonance with the later development of pianoforte playing. The steel strings are stretched over the longer part, and the covered bass strings (lying above the steel ones), rest on the shorter bridge, which in fig. 3 will be distinguished behind the others and nearer the end of the case. The wrest-plank bridge to which the strings are pinned down to prevent their being forced upwards by the blow of the hammer, is the point from which the vibrating length of the string is measured.
5(6) The action, situated beyond the keys under the wrest plank, comprises the complex system of levers, hammers, checks, dampers, etc., which are set working when a key is depressed) see figs. 4, 5, 6). To describe minutely this action, which differs in details according to the various
