The use of these double corners produced something else that was new. This was the curving of the ribs at the waist forming a hollowed-out place called bouts; and these bouts gave the right hand of the player more freedom to move up and down with the bow. Up to this time the position of the performer’s hand was stiff and cramped unless there was a tremendously high bridge to carry the strings. So when the ribs were curved and the bouts cut, the player’s hand could move more easily and naturally. But even so, the shape of the violin was not fully determined. These bouts were made according to the idea of every individual maker. They were small and deep in some instruments, long and shallow in others. They were often of enormous size and out of all proportion to the general form of the instrument. Pictures of these old models look very queer to us now. About the beginning of the Sixteenth Century long and shallow bouts were universally used and the violin began to take the simple and graceful form with the double corners with which we are familiar. But, notwithstanding all these improvements, we have not yet arrived at our perfect violin. The sound-holes, those two curved openings called _f_-holes, on either side of the bridge, were not yet in their proper place. These _f_-holes were subject to a great deal of experimenting. Strange to say in the old _vielle_, or _viole_, of the Troubadours they were often very nearly in the place they occupy to-day, that is to say partly in the waist and partly in the lower part of the instrument; but the invention of the bouts displaced them, and, sometimes (indeed very often), they appear right down at the very bottom of the instrument near the tail-piece, as you will see if you look at the picture facing page 70. Makers had an idea that the belly should be left as strong as possible and that the cutting of these _f_-holes made it weaker. At first they used a round sound-hole, like that of a guitar, right in the middle of the instrument. Then they made a pair of crescents, or large C’s turned face to face, as you will see if you look at the Angel playing in the picture of St. Cecilia facing page 18; and they liked this so much that they used these C’s for a hundred years (in the Fourteenth and Fifteenth Centuries). Then came the “flaming-sword” as in the _viola d’amore_ facing page 50; and then the _f_-hole. But at first the _f_’s were placed back to back. Finally, about 1580, the Italian makers cut their _f_-holes front to front. By the middle of the Seventeenth Century, about the time that our own country was being settled by the English and Dutch, the violin was ready for the great makers to improve it in beauty of outline and qualities of tone. The violin is, therefore, almost exactly the age of our own country! * * * * *
