Gerolamo Frescobaldi was the greatest and most important of all Italian organists. He was born, 1587, at Ferrara, and studied under Alessandro Milleville, also a native of Ferrara. Quadrio tells us that he possessed a singularly beautiful voice, and it is certain that while still a youth, he enjoyed a great reputation both as singer and organist. In 1516 he went to Rome, and before long was appointed regular organist at St. Peter's. His first performance there, according to Baini, attracted an audience of thirty thousand persons. Frohberger, the great German organist and composer, was Frescobaldi's pupil from 1637 to 1641, and thus the noble style of Italian organ playing was handed on to other schools. His compositions are important and give us a high idea of his powers. He was the first to play fugues on the organ. His works consist chiefly of organ-compositions, which even to-day are considered worthy the attention of students of that instrument. Other great Italian masters of the sixteenth and seventeenth centuries, distinguished and gifted composers for the organ, were Girolamo, Parabosco, Andrea and Giovanni Gabrieli, and Merulo.

The famous Italian makers have earned a well deserved immortality, and never were their instruments as highly prized as now. The parent of the violin was the rebec, specimens of which may still be seen in numerous museums. We find indications of the use of the rebec in the twelfth and thirteenth centuries. In manuscripts of that period it is represented as not unlike the mandolin in form, with trefoil sound-holes, and a carved head in the place of the modern scroll. It was fitted with three strings and was played with a bow of somewhat rounded form. The leading-spirit of the Amati family was Andrea Amati (1520-1577), whose improvements upon the stringed instruments made at Brescia by Maggini and Gasparo da Salo, the most celebrated artists of the still older Brescian school, prepared the way for that perfection that was so soon to be attained. Andrea's brother, the elder Nicolo, confined his attention chiefly to the bass viol. Antonio (1565-1670) and Geronimo, Andrea's two sons, carried out their father's ideas with intelligence and zeal; but the greatest genius of all was Geronimo's son, the second Nicolo (1596-1648), whose best works are simply priceless. Under his son, another Geronimo, the celebrity of the house declined, never to rise again.
