In the early part of his life, he published “_Sonate a Violino e Violoncello, o Cembalo, Opera Prima_.” This, and his Opera Seconda, of _Six Sonatas_ or _Solos_ for the same instrument, and another work entitled “_XVIII Concerti a cinque Stromenti_,” were all published by Le Cène, of Amsterdam, and prove him to have been a truly excellent composer. Such, however, was the ascendancy of Corelli’s name, and so ambitious was Tartini of being thought a follower of the precepts and principles of that master, that, during the zenith of his own reputation, he refused to teach any other music to his pupils, till they had studied the _Opera Quinta_, or _Solos_, of Corelli; and the excellence of this foundation was made manifest by the result. His favorite pupils were Bini and Nardini. These, as well as others of Tartini’s _élèves_, formed, in their turn, scholars of great abilities, who contributed to spread his reputation and manner of playing all over Europe. Tartini’s own first master was an obscure musician, of the name of Giulio di Terni, who afterwards made a fitting change of position, and descended into the pupil of his own scholar—a circumstance related by Tartini himself, who used to say that he had studied very little till after he was thirty years of age[26]. At the age of fifty-two, Tartini made a marked alteration in his style of playing, from extreme difficulty (or what was _then_ so considered) to grace and expression. His method of executing an adagio has been represented by his contemporaries as inimitable, and was almost, in their idea, supernatural—an impression to which the idea of the patron saint must have not a little conduced. The particulars that have been preserved respecting his scholar, Pasquale Bini, are not without interest. Recommended to him at the age of fifteen, by Cardinal Olivieri, Tartini found him a youth after his own heart, possessing excellent moral dispositions, as well as musical; and he accordingly cherished a very marked regard for him. This young musician practised with such assiduity, that, in three or four years, he vanquished the most difficult of Tartini’s compositions, and executed them with greater force than the author himself. When he had finished his studies, his patron, Cardinal Olivieri, took him to Rome, where he astonished all the Professors by his performance,—particularly Montagnari, at that time the principal violinist there; and it is generally believed, that Montagnari was so mortified by the superiority, as to have died of grief! When informed that Tartini had changed his style and taste in playing, Bini returned to Padua, “Nil actum reputans, si quid superesset agendum,”— and placed himself for another year under that excellent and worthy master; at the end of which period, so intense had been his application, that he played with a degree of certainty and expression truly wonderful.
