But the dominion of church counterpoint was not to be overthrown at once; and so we find that the first clearly defined instrumental form was the "toccata." Those of Claudio Merulo, a Venetian organist, printed in 1598, were the first to be published. They were written for the organ, and resembled Willaert's church vocal music in that they consisted of running or polyphonic passages, followed by successions of broad chords. Giovanni Gabrieli did more, perhaps, than any other of the Venetians to lead instrumental music toward the modern style. He wrote what he called "canzone;" and in these compositions the melody assumed a position of importance. Furthermore, he showed a tendency to make his melodic themes recur at regular intervals, although he had no well-defined system. Still, he made important advances. The Roman school of organists made valuable contributions to the development of instrumental music. Girolamo Frescobaldi (1591-1640) wrote ricercari in which there was something like a systematic employment of clear melodic themes. He wrote canzone in which there were passages slightly resembling the choral hymns of the Reformation; and in his "Capriccio Chromatico" he made a bold use of chromatic harmonies. Indeed, his music shows a general tendency toward the modern major and minor keys. We are not surprised, then, to find in the works of Bernardo Pasquine (1637-1710) arpeggios (running passages composed of the notes of chords, much used in modern piano music), flowing passages for both hands, and repetitions of the thematic ideas. But the manner of composing for the clavichord and harpsichord had been so greatly influenced at this time by the evolution of a distinct method of playing the instruments that we must, before advancing any further, go back and briefly review that topic. The first systematic method of playing the organ and harpsichord was set forth in 1593 in a book by Girolamo di Ruta, a Venetian, and it contained rules for fingering which were in use for more than a century. A work by Lorenzo Penna, published at Bologna in 1656, shows very clearly what the general principles of clavichord and harpsichord technic were in that day. "In ascending the fingers of the right hand move one after the other,--first the middle, then the ring finger, again the middle, and so on in alternation. Care must be taken that the fingers do not strike against one another. In descending, the middle, followed by the index finger, is used. The left hand simply reverses this process. The rule for the position of the hands is that they shall never lie lower than the fingers, but shall be held high, with the fingers stretched out." This style of fingering held its own until Bach's time. It was in existence as late as 1741, though more fingers were employed. But the fingers were still held straight, and the thumb was not used.
