The next important feature of the internal organism is the sound-post, which serves many purposes. It is the medium by which the vibratory powers of the instrument are set in motion; it gives support to the right side of the belly, it transmits vibrations, and regulates both the power and quality of tone. The terms used for this vital factor of a Violin on the Continent at once prove its importance. The Italians and French call it the "Soul," and the Germans the "Voice." If we accept the bass-bar as the nervous system of a Violin, the sound-post may be said to perform the functions of the heart with unerring regularity. The pulsations of sound are
20
regulated by this admirable contrivance. If mellowness of quality be sought, a slight alteration of its position or form will produce
a favourable change of singular extent; if intensity of tone be requisite, the sound-post is again the regulator. It must, of course, be understood that its power of changing the quality of the tone is limited in proportion to the constitutional powers of the instrument in each case. It is not pretended that a badly constructed instrument can be made a good one by means of this subtle regulator, any more than a naturally weak person can be made robust by diet and hygiene.
The position of the sound-post is usually one-eighth to three-eighths of an inch behind the right foot of the bridge, the distance being variable according to the model of the instrument. If the Violin be high-built, the post requires to be nearer the bridge, that its action may be stronger; whilst flat-modelled instruments require that the post be set further away from the bridge. It is not possible
to have any uniform arrangement of the sound-post in all instruments; as we have remarked before in reference to the bass-bar, the variations in the thickness, outline, model, &c., of the Violin are so frequent as to defy identity of treatment; uniformity has been sought for, but without success.
The post can only be adjusted by a skilful workman, who either plays himself or has the advantage of having the various adjustments tested by a performer. The necessity of leaving this exceedingly delicate matter in practised hands cannot be too strongly impressed upon the amateur, for the damage done in consequence of want of skill is often irreparable.
There are two methods of setting the sound-post in the instrument: the first fixes it in such a position as to place the grain of the
post parallel with the grain of the belly; the second sets it crosswise.
The next important feature to be mentioned is the bridge, which forms no small part of the vibrating mechanism of the instrument, and needs the utmost skill in its arrangement. Its usual position is exactly between the two small niches marked in each sound-hole, but this arrangement is sometimes altered in the case of the stop being longer or shorter. Many forms of bridges have been in use
at different periods, but that now adopted is, without doubt, the best. In selecting a bridge great care is requisite that the wood be suitable to the constitution of the Violin. If the instrument is wanting in brilliancy, a bridge having solidity of fibre is necessary; if wanting in mellowness, one possessing soft qualities should be selected.
We now pass to the neck of the Violin, which is made of sycamore or plane-tree. Its length has been increased since the days of the great Italian masters, who seem to have paid but little attention to this portion of the instrument, in regard to its appearance and as to the wood used for its manufacture, which was of the plainest description. It may be observed that in those times the florid pas-
sages which we now hear in Violin music were in their infancy, the first and second positions being those chiefly used; hence the little attention paid to the handle of the instrument. Modern requirements have made it imperative that the neck should be well shaped, neither too flat nor too round, but of a happy medium. The difficulties of execution are sensibly lessened when due attention is paid to this requirement.
The fingerboard is of ebony, and varies a little in length according to the position of the sound-holes. To form the board properly is a delicate operation, for if it be not carefully made the strings jar against it, and the movements of the bow are impeded. The nut, or rest, is that small piece of ebony over which the strings pass on the fingerboard.
The purfling is composed of three strips of lime-tree, two of which are stained black. Whalebone purfling has been frequently used,
particularly by the old Amsterdam makers.
The principal parts of the instrument have now been described, and there remain only the pegs, blocks, strings, and tail-piece, the sum of which makes up the number of fifty-eight constituent parts as before mentioned. There is still, however, one item of the construction to be mentioned which does not form a separate portion of the Violin, but which is certainly worthy of notice, viz., the button, which is that small piece of wood against which the heel of the neck rests. The difficulty of making this apparently insignificant piece can only be understood by those who have gone through the various stages of Violin manufacture. The amount of finish given to the button affects in a great measure the whole instrument, and if there is any defect of style it is sure to be apparent here.
It is a prominent feature, and the eye naturally rests upon it: as the key-stone to the arch, so is the button to the Violin.
The sound-holes, or f-holes, it is almost needless to remark, are features of vital importance. Upon the form given to them, and the manner of cutting them, largely depend the volume and quality of tone. The Italian makers of Brescia and Cremona appear to have been aware of the singular influence the formation of the sound-hole has upon the production and quality of sound. The variety of original shapes they gave to them is evidence of their knowledge. Appearance in keeping with the outline of their design may have influenced them in some measure, but not entirely. Most makers used patterns from which to cut their sound-holes; Joseph Guarneri and some others appear to have drawn them on the belly, and cut them accordingly.
From the foregoing remarks upon the various portions of the Violin it may be assumed that the reader has gained sufficient insight
21
into the process of its manufacture to enable him to dispense with a more minute description of each stage.
In conclusion, I cannot refrain from cautioning possessors of good instruments against entrusting them into the barbaric hands of pretended repairers, who endeavour to persuade them into the belief that it is necessary to do this, that, and the other for their benefit. The quack doctors of the Violin are legion--they are found in every town and city, ready to prey upon the credulity of the lov-ers of Fiddles, and the injury they inflict on their helpless patients is frequently irreparable. Unfortunately, amateurs are often prone to be continually unsettling their instruments by trying different bars, sound-posts, &c., without considering the danger they run
of damaging their property instead of improving it. Should your instrument need any alteration, no matter how slight, consult only those who have made the subject a special study. There are a few such men to be found in the chief cities of Europe, men whose love for the instrument is of such a nature that it would not permit them to recommend alterations prejudicial to its well-being.
SECTION III
Italian and other Strings
Upon the strings of the Violin depends in a great measure the successful regulation of the instrument. If, after the careful adjustment of bridge, sound-post, and bass-bar, strings are added which have not been selected with due care and regard to their relative proportion, the labour expended upon the important parts named is at once rendered useless. Frequently the strings are the objects least considered when the regulation of a Violin is attempted; but if this be the case, results anything but satisfactory ensue. It is, therefore, important that every Violinist should endeavour to make himself acquainted with the different varieties and powers of strings, that he may arrange his instrument with due facility.
The remarkable conservatism attending the structural formation of the Violin exists more or less in the appliances necessary for the awakening of its dormant music. If we turn to its pegs, we find them of the same character as the peg of its far-removed ancestor, the monochord; and if we compare the Italian peg of the seventeenth century with a modern one, the chief difference lies in the latter being more
