England alone surpasses the United States in the number of pianos annually manufactured. In 1852, the one hundred and eighty English makers produced twenty-three thousand pianos,--fifteen hundred grands, fifteen hundred squares, and twenty thousand uprights. As England has enjoyed fifteen years of prosperity since, it is probable that the annual number now exceeds that of the United States. The English people, however, pay much less money for the thirty thousand pianos which they probably buy every year, than we do for our twenty-five thousand. In London, the retail price of the best Broadwood grand, in plain mahogany case, is one hundred and thirty-five guineas; which is a little more than half the price of the corresponding American instrument. The best London square piano, in plain case, is sixty guineas,--almost exactly half the American price. Two thirds of all the pianos made in England are low-priced uprights,--averaging thirty-five guineas,--which would not stand in our climate for a year. England, therefore, supplies herself and the British empire with pianos at an annual expenditure of about eight millions of our present dollars. American makers, we may add, have recently taken a hint from their English brethren with regard to the upright instrument. Space is getting to be the dearest of all luxuries in our cities, and it has become highly desirable to have pianos that occupy less of it than the square instrument which we usually see. Successful attempts have been recently made to apply the new methods of construction to the upright piano, with a view to make it as durable as those of the usual forms. Such a brisk demand has sprung up for the improved uprights, that the leading makers are producing them in considerable numbers, and the Messrs. Steinway are erecting a new building for the sole purpose of manufacturing them. The American uprights, however, cannot be cheap. Such is the nature of the American climate, that a piano, to be tolerable, must be excellent; and while parts of the upright cost more than the corresponding parts of the square, no part of it costs less. Six hundred dollars is the price of the upright in plain rosewood case,--fifty dollars more than a plain rosewood square.
