Lorraine and brother of Louise de Vaudemont, Henry III.'s queen. His

wife, Mary of Luxemburg, descended from the dukes of Brittany, and he

sovereignty, and called his son prince and duke of Brittany.

GUITAR (Fr. _guitarre_, Ger. _Guitarre_, Ital. _chitarra_, Span.

_guitarra_), a musical instrument strung with gut strings twanged by the

fingers, having a body with a flat back and graceful incurvations in

complete contrast to the members of the family of lute (i.e.), whose

back is vaulted. The construction of the instrument is of paramount

importance in assigning to the guitar its true position in the history

of musical instruments, midway between the cithara (i.e.) and the

violin. The medieval stringed instruments with neck fall into two

classes, characterized mainly by the construction of the body: (1) Those

which, like their archetype the cithara, had a body composed of a flat

or delicately arched back and soundboard joined by ribs. (2) Those

which, like the lyre, had a body consisting of a vaulted back over which

was glued a flat soundboard without the intermediary of ribs; this

method of construction predominates among Oriental Instruments and is

greatly inferior to the first. A striking proof of this inferiority is

afforded by the fact that instruments with vaulted backs, such as the

rebab or rebec, although extensively represented during the middle ages

in all parts of Europe by numerous types, have shown but little or no

development during the course of some twelve centuries, and have dropped

out one by one from the realm of practical music without leaving a

single survivor. The guitar must be referred to the first of these

classes.

The back and ribs of the guitar are of maple, ash or cherry-wood,

frequently inlaid with rose-wood, mother-of-pearl, tortoise-shell, &c.,

while the soundboard is of pine and has one large ornamental rose sound

hole. The bridge, to which the strings are fastened, is of ebony with an

ivory nut which determines the one end of the vibrating strings, while

the nut at the end of the fingerboard determines the other. The neck and

fingerboard are made of hard wood, such as ebony, beech or pear. The

head, bent back from the neck at an obtuse angle contains two parallel

barrels or long holes through which the pegs or metal screws pass, three

on each side of the head. The correct positions for stopping the

intervals are marked on the fingerboard by little metal ridges called

frets. The modern guitar has six strings, three of gut and three of silk

covered with silver wire, tuned as shown. To the thumb are assigned the

three deepest strings, while the first, second and third fingers are

used to twang the highest strings. It is generally stated that the sixth

or lowest string was added in 1790 by Jacob August Otto of Jena, who was

the first in Germany to take up the construction of guitars after their

introduction from Italy in 1788 by the duchess Amalie of Weimar. Otto[1]

states that it was Capellmeister Naumann of Dresden who requested him to

make him a guitar with six strings by adding the low E, a spun wire

string. The original guitar brought from Italy by the duchess Amalie had

five strings,[2] the lowest A being the only one covered with wire. Otto

also covered the D in order to increase the fulness of the tone. In

Spain six-stringed guitars and vihuelas were known in the 16th century;

they are described by Juan Bermudo[3] and others.[4] The lowest string

was tuned to G. Other Spanish guitars of the same period had four, five

or seven strings or courses of strings in pairs of unisons. They were

always twanged by the fingers.
