Regarding the combination of the violin with other instruments we know that at the end of the fifteenth century there existed in Louvain an ‘orchestra’ composed of a harp, a flute, a _viol_, and a trumpet. There is recorded an account of another ‘orchestra’ belonging to Duke Hercules in Ferrara, who employed a great number of musicians. It included flutes, trumpets, lutes, trombones, harps, viols and rebecs. We should not assume, however, that all of these instruments were played simultaneously. Each class of instrument had its own part and if all of them played together they must have made noise rather than music. We are also informed that previous to the year 1450 popes and princes employed ‘orchestras’ which combined ‘the voices, organ, and _other_ instruments into the loveliest harmony.’ In spite of the almost entire lack of music for the violin we know that it was a favorite instrument and consequently that the players must have produced on it pleasing music of some kind. Indication of its popularity is found in the works of Fra Angelico (1387-1455), whose famous angel holds a viol in her hands, and in Boccaccio’s novels, where we learn that violin music formed a considerable part of the entertainment of all classes. II The sixteenth century brought the violin to a perfection that was still far in advance of the technique of the players. At the same time there was a distinct advancement in the recognition of instrumental music, although vocal music continued to maintain its preeminence. This was due partly to the limited technique of the instrumentalists and partly to the greater appeal of music wedded to words. Violin players then knew nothing about changing of positions and therefore could play only in the first position.[44] Thus the tone register of the violin was small. Some players, however, attempted to reach higher tones on the first string through the stretching of the fourth finger. Simple melodic phrases or figures were lacking in even quality of tone, in smoothness and in fluency. The art of legato playing was unknown and violinists could not play two or more notes with ‘one bow.’ Neither did they endeavor to conquer the technical difficulties of playing on the G string. They made practically no use of the fourth string until the end of the century. In addition, the instruments were badly constructed, equipped with strings of inferior quality and tuned in a low pitch, all of which militated strongly against purity and accuracy of intonation. Hans Gerle (a flute player of Nuremberg), in his ‛_Musica Teutsch, auf die Instrument der grossen und kleinen Geigen_’ (1532), advised that intonation marks be placed on the fingerboard, and this naïve advice was in use as late as the middle of the eighteenth century.[45]
