the body at the treble end of the instrument, and joins the pillar at the bass end. In it are set the tuning pins round which the strings are wound. The neck further comprises two brass plates, sometimes called the comb, which conceal part of the mechanism for shortening the strings, and producing additional semitones by the agency of the pedals. On the front brass plate (to the left of the player are to be seen first a row of brass bridges, against which the strings rest on leaving the tuning pins, and which determine the length of the string from the peg in the soundboard; secondly the two rows of brass discs called forks, connected by steel levers, each disc furnished with two studs for grasping the string and shortening it. If you watch these while the harp is being played, you will see that when the pedal is depressed to first notch, the lower disc tarns a little away on an arbor or mandrel, still keeping the studs clear of the string, the external steel levers are set in motion, and the result is that the upper disc revolves also till the string is caught between the two studs and shortened; if the same pedal be pressed down to the second notch, the lower disc revolves again till the string is a second time grasped and shortened, the upper disc remaining motionless the while. The reason for this is that each pedal is a lever set upon a spring, and by depressing the pedal, the pedal rod in the pillar is drawn down, setting in motion the chains and arbors connected with its upper extremity and situated within the brass plates, with the visible result described above.

The strings are of gut in the middle and upper registers, and of covered steel wire in the bass; the C strings are red and the F blue; the strings are usually forty-six in number, and are arranged in the diatonic scale of C flat major.
