WILLIAM CORBETT, a member of the King’s band, and a violinist of celebrity, who was the leader of the first Opera orchestra in the Haymarket, at the time when “Arsinoe” was performed there. In the year 1710, when the Italian Opera, properly so called, was established (with “Rinaldo” for its initiatory piece), a set of instrumental performers were expressly introduced, and Corbett, though in the service of the King, was permitted to go abroad. Visiting Rome, where he resided many years, he made a valuable collection of music and musical instruments. Some persons, professing to be acquainted with his circumstances, and fidgetting themselves to account for his being able to lay out such sums as he was observed to do, in the purchase of books and instruments, asserted pretty roundly that he had an allowance from Government, besides his salary, with the commission to watch the motions of the Pretender! This anxiety to construe fiddling into politics, and to find the heart of a state-mystery in the head of a violinist, is of a piece with what has been already related as to Rode and Viotti.—Returning from Italy about the year 1740, Corbett brought over with him a great quantity of music which he had composed abroad. Full of ambition to print, and desire to profit, he issued proposals for publishing by subscription a work entitled “Concertos, or universal _Bizarreries_, composed on all the new _gustos_, during many years’ residence in Italy.” This strange medley he dragged into publication; but buyers were few and shy. It was in three books, containing thirty-five Concertos of seven parts, in which he professed to have imitated the style of the various kingdoms in Europe, and of several cities and provinces in Italy. In his earlier days, before he left England, he published, in a soberer vein, two or three sets of _Sonatas for Violins and Flutes_,—twelve _Concertos for all Instruments_, and several sets of what were called _Tunes for the Plays_. Corbett died, at an advanced age, in the year 1748, bequeathing by his will the best of his instruments to Gresham College, with a salary of ten pounds a-year to a female servant, who was to act in the demonstrative character. Her expositions of the merits of this collection, are not to be confounded with the “Gresham Lectures.”
