drama, which just at that period had come to be well known, became more and more urgent. Imbued with the spirit of that age, the whole tendency of which was to exalt the ancient classic poets, a circle of men of science and culture from the higher classes gave themselves to the task of producing a style of music such as the Greeks must have had in the representation of their dramas. In the mansion of Count _Bardi_, in Florence, then the centre of union for all who had any claims to cultivation, music was first arranged for a _single_ voice by a dilettante, the father of the renowned Galileo. This attempt met with applause and imitation among the most distinguished singers of the time, who thenceforth turned their attention also to secular music. It thus came about that, towards the end of the sixteenth century, on festal occasions in Italy, and even earlier in France, theatrical representations were given with vocal music. This music was, however, always composed in the form of the chorus, and the leading voice alone was represented by a singer; the other voices were represented by instruments. Such was the beginning of solo singing, which, growing ever more in public favor, soon came to be introduced into the most solemn church music; dramatic representations, religious and secular, grew very popular, and were the forerunners of the opera and oratorio, the richest inventions of the sixteenth century. Up to this time, a singer of sound musical culture sufficed for chorus singing, but by the introduction of solo singing a more complete education of the organ of singing became a necessity. Indeed, as early as the middle of the fifteenth century there existed in Rome and Milan schools of music and professorships for the education of singers; but with the introduction and diffusion of solo singing similar conservatories were established in nearly all the more considerable cities of Italy, and all the energies of the musician were devoted to the highest possible culture of the voice. But, with solo singing, greater attention was paid to instruments, which were already in those days constructed with the greatest care and skill. With the higher cultivation of single voices, chorus singing also became richer in harmony and embellishment, but as, in vocal music, words accompany the music, the expression of the music becomes more definite and intelligible for the hearer, and thus with the higher cultivation of vocal music, and by means of it, even our whole modern system of harmony has been developed.
