FRANÇOIS TOURTE
“The Stradivari of the bow”
The world was slow to adopt Tourte’s bow; and it was not until Paganini (1784-1840), the Italian wizard, came on the stage that a revolution in violin-playing took place. Paganini used every imaginable movement of the bow and developed the flexibility of the wrist. Then a new School of violin-playing arose and violin-playing gradually developed into what it is to-day.
“Tourte’s first experiments are said to have been made from the staves of old sugar hogsheads from Brazil. This is not unlikely. Probably the best slabs of Brazil-wood employed for this purpose had acquired a certain additional elasticity from the combined effect of exposure to tropical heat and the absorption of the saccharine juices.
“It is certain that the greater elasticity which he secured in the stick by the choice and preparation of the wood, enabled him to carry out to the fullest extent the method of bending the stick of the bow the reverse way, that is, inwards, and thus to realize what had long been the desideratum of a violinist,—a bow which should be strong and elastic without being heavy. By thus increasing and economising the resistance of the stick, he liberated the player’s thumb and fingers from much useless weight. By a series of patient experiments he determined the right curvature for the stick and the rule for tapering it gradually towards the point so as to have the centre of gravity in the right place, or, in other words, to ‘balance’ properly over the strings in the hands of the player. He determined the true length of the stick and the height of the point and the nut, in all which particulars the bow-makers of his time seem to have erred on the side of excess. Lastly he invented the method of spreading the hairs and fixing them on the face of the nut by means of a moveable band of metal fitted on a slide of mother-of-pearl.”[9]
Tourte’s violin bows are from 29 to 29½ inches long; a viola bow is 29 inches; and a ’cello bow is from 28½ to 28¾ inches. The stick of a violin bow is made of Brazilian snake wood, or lance wood, reddish and slightly mottled. It is cut straight, following the grain of the wood and then it is slightly bent by the application of heat. The hair, fastened into the tip by a plug, is inserted into the nut of the bow (made of ebony, or tortoise shell); it can be made tighter, or looser, by turning the screw in the nut. There are from 175 to 200 hairs in a bow and these are taken from tails of stallions. White hair is used for the violin, viola and violoncello and black for the double-bass. Rosin is rubbed on the bow to increase its friction.
A violinist takes just as much care of his bow as he does of his violin. When he has finished playing, he wipes his violin carefully with a silk handkerchief before he places it tenderly in the case; then he unscrews his bow and places it in the rests in the top of the case.
