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_).

[Illustration]

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.

[Illustration]

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.
