Musical Instruments :: CHAPTER VIII.

CHAPTER VIII.

The construction of the organistrum requires but little explanation. A glance at the finger-board reveals at once that the different tones were obtained by raising the keys placed on the neck under the strings, and that the keys were raised by means of the handles at the side of the neck. Of the two bridges shown on the body, the one situated nearest the middle was formed by a wheel in the inside, which projected through the sound-board. The wheel which slightly touched the strings vibrated them by friction when turned by the handle at the end. The order of intervals was c, d, e, f, g, a, b-flat, b-natural, c, and were obtainable on the highest string. There is reason to suppose that the other two strings were generally tuned a fifth and an octave below the highest. The organistrum may be regarded as the predecessor of the hurdy-gurdy, and was a rather cumbrous contrivance. Two persons seem to have been required to sound it, one to turn the handle and the other to manage the keys. Thus it is generally represented in mediÆval concerts.

The monochord (p. 100) was mounted with a single string stretched over two bridges which were fixed on an oblong box. The string could be tightened or slackened by means of a turning screw inserted into one end of the box. The intervals of the scale were marked on the side, and were regulated by a sort of movable bridge placed beneath the string when required. As might be expected, the monochord was chiefly used by theorists; for any musical performance it was but little suitable. About a thousand years ago when this monochord was in use the musical scale was diatonic, with the exception of the interval of the seventh, which was chromatic inasmuch as both b-flat and b-natural formed part of the scale. The notation on the preceding page exhibits the compass as well as the order of intervals adhered to about the tenth century.

This ought to be borne in mind in examining the representations of musical instruments transmitted to us from that period.

As regards the wind instruments popular during the middle ages, some were of quaint form as well as of rude construction.

The chorus, or choron, had either one or two tubes, as in the woodcut page 101. There were several varieties of this instrument; sometimes it was constructed with a bladder into which the tube is inserted; this kind of chorus resembled the bagpipe; another kind resembled the poongi of the Hindus, mentioned page 51. The name chorus was also applied to certain stringed instruments. One of these had much the form of the cithara, page 86. It appears however, probable that chorus or choron originally designated a horn (Hebrew, Keren; Greek, Keras; Latin, cornu).

The flutes of the middle ages were blown at the end, like the flageolet. Of the syrinx there are extant some illustrations of the ninth and tenth centuries, which exhibit the instrument with a number of tubes tied together, just like the Pandean pipe still in use. In one specimen engraved (page 102) from a manuscript of the eleventh century the tubes were inserted into a bowl-shaped box. This is probably the frestele, fretel, or fretiau, which in the twelfth and thirteenth centuries was in favour with the French mÉnÉtriers.

Some large Anglo-saxon trumpets may be seen in a manuscript of the eighth century in the British museum. The largest kind of trumpet was placed on a stand when blown. Of the oliphant, or hunting horn, some fine specimens are in the South Kensington collection. The sackbut (of which we give a woodcut) probably made of metal, could be drawn out to alter the pitch of sound. The sackbut of the ninth century had, however, a very different shape to that in use about three centuries ago, and much more resembled the present trombone. The name sackbut is supposed to be a corruption of sambuca. The French, about the fifteenth century, called it sacqueboute and saquebutte.

The most important wind instrument—in fact, the king of all the musical instruments—is the organ.

The pneumatic organ is sculptured on an obelisk which was erected in Constantinople under Theodosius the great, towards the end of the fourth century. The bellows were pressed by men standing on them: see page 103. This interesting monument also exhibits performers on the double flute. The hydraulic organ, which is recorded to have been already known about two hundred years before the Christian era, was according to some statements occasionally employed in churches during the earlier centuries of the middle ages. Probably it was more frequently heard in secular entertainments for which it was more suitable; and at the beginning of the fourteenth century appears to have been entirely supplanted by the pneumatic organ. The earliest organs had only about a dozen pipes. The largest, which were made about nine hundred years ago, had only three octaves, in which the chromatic intervals did not occur. Some progress in the construction of the organ is exhibited in an illustration (engraved p. 104) dating from the twelfth century, in a psalter of Eadwine, in the library of Trinity college, Cambridge. The instrument has ten pipes, or perhaps fourteen, as four of them appear to be double pipes. It required four men exerting all their power to produce the necessary wind, and two men to play the instrument. Moreover, both players seem also to be busily engaged in directing the blowers about the proper supply of wind. Six men and only fourteen pipes! It must be admitted that since the twelfth century some progress has been made, at all events, in the construction of the organ.

The pedal is generally believed to have been invented by Bernhard, a German, who lived in Venice about the year 1470. There are, however, indications extant pointing to an earlier date of its invention. Perhaps Bernhard was the first who, by adopting a more practicable construction, made the pedal more generally known. On the earliest organs the keys of the finger-board were of enormous size, compared with those of the present day; so that a finger-board with only nine keys had a breadth of from four to five feet. The organist struck the keys down with his fist, as is done in playing the carillon still in use on the continent, of which presently some account will be given.

Of the little portable organ, known as the regal or regals, often tastefully shaped and embellished, some interesting sculptured representations are still extant in the old ecclesiastical edifices of England and Scotland. There is, for instance, in Beverley minster a figure of a man playing on a single regal, or a regal provided with only one set of pipes; and in Melrose abbey the figure of an angel holding in his arms a double regal, the pipes of which are in two sets. The regal generally had keys like those of the organ but smaller. A painting in the national Gallery, by Melozzo da Forli who lived in the fifteenth century, contains a regal which has keys of a peculiar shape, rather resembling the pistons of certain brass instruments. The illustration has been drawn from that painting. To avoid misapprehension, it is necessary to mention that the name regal (or regals, rigols) was also applied to an instrument of percussion with sonorous slabs of wood. This contrivance was, in short, a kind of harmonica, resembling in shape as well as in the principle of its construction the little glass harmonica, a mere toy, in which slips of glass are arranged according to our musical scale. In England it appears to have been still known in the beginning of the eighteenth century. Grassineau describes the “Rigols” as “a kind of musical instrument consisting of several sticks bound together, only separated by beads. It makes a tolerable harmony, being well struck with a ball at the end of a stick.” In the earlier centuries of the middle ages there appear to have been some instruments of percussion in favour, to which Grassineau’s expression “a tolerable harmony” would scarcely have been applicable. Drums, of course, were known; and their rhythmical noise must have been soft music, compared with the shrill sounds of the cymbalum; a contrivance consisting of a number of metal plates suspended on cords, so that they could be clashed together simultaneously; or with the clangour of the cymbalum constructed with bells instead of plates; or with the piercing noise of the bunibulum, or bombulom; an instrument which consisted of an angular frame to which were loosely attached metal plates of various shapes and sizes. The lower part of the frame constituted the handle: and to produce the noise it evidently was shaken somewhat like the sistrum of the ancient Egyptians. We give woodcuts of the three instruments.

The triangle nearly resembled the instrument of this name in use at the present day; it was more elegant in shape and had some metal ornamentation in the middle.

The tintinnabulum consisted of a number of bells arranged in regular order and suspended in a frame.
