SERPENT (Lat. serpens, creeping, from serpere; cf. "reptile " from repere, Gr.4 ml-eta) , a synonym for reptile or snake (see REPTILE, and SNAKES
WORSHIP below.In music the serpent (Fr. serpent, Ger. Serpent, Schlangenrohr, Ital. serpentone) is an obsolete bass wind instrument derived from the old wooden cornets (Zinken), and the progenitor of the bass-horn, Russian bassoon and ophicleide. The serpent is composed of two pieces of wood
diameter varying from a little over half an inch at the crook to nearly 4 in. at the wider end. The tube is covered with leather to ensure solidity. The upper extremity ends with a bent brass tube or crook, to which the cup-shaped mouthpiece is attached; the lower end does not expand to form a bell, a peculiarity the serpent shared with the cornets. The tube is pierced laterally with six holes, the first three of which are covered with the fingers of the right hand and the others with those of the left. When all the holes are thus closed the instrument will produce the following sounds, of which the first is the fundamental and the rest the harmonicseries founded thereon:;=8 Each of the holes on being successively opened gives the same series of harmonics on a new. fundamental, thus producing a chromatic compass of three octaves by means of six holes only. The holes are curiously disposed along the tube for convenience in reaching them with the fingers; in consequence they are of very small diameter , and this affects the intonation and timbre of the instrument adversely. With the application of keys to the serpent, which made it possible to place the holes approximately in the correct theoretical position, whereby the diameter of the holes was also made proportional to that of the tube, this defect was remedied and the timbre improved.The serpent was, according to Abbe Lebceuf,' the outcome of experiments made on the cornon, the bass cornet or Zinke, by Edme Guillaume, canon of Auxerre, in 1590. The invention at once proved a success, and the new bass became a valuable addition to church concerted music, more especially in France, in spite of the serpent's harsh, unpleasant tone. Mersenne (1636) describes and figures the serpent of his day in detail, but it was evidently unknown to Praetorius (1618). During the 18th century the construction of the instrument underwent many improvements, the tendency being to make the unwieldy windings more compact. At the beginning of the 19th century the open holes had been discarded, and as many as fourteen or seventeen keys disposed conveniently along the tube. Gerber, in his Lexikon (1790), states that in 178o a musician of Lille, named Regibo, making further experiments on the serpent, produced a bass horn, giving it the shape of the bassoon for greater portability; and Frichot, a French refugee in London, introduced a variant of brass which rapidly won favour under the name of " bass horn " or " basson russe " in English military bands. On being introduced on the continent of Europe, this instrument was received into general use and gave a fresh impetus to experiments with basses for military bands, which resulted first in the ophicleide (q.v.) and ultimately in the valuable invention of the piston or valve. Further information as to the technique and construction of the serpent may be gained from Joseph Frohlich's excellent treatise 1 See Memoire concernant l'histoire ecclesiastique et civile d'Auxerre (Paris, 1848), ii. 189.on all the instruments
