The trade in new pianos, however, is nothing to the countless transactions in old. Here figures are impossible; but probably ten second-hand pianos are sold to one new one. The business of letting pianos is also one of great extent. It is computed by the well-informed, that the number of these instruments now "out," in the city of New York, is three thousand. There is one firm in Boston that usually has a thousand let. As the rent of a piano ranges from six dollars to twelve dollars a month,—cartage both ways paid by the hirer,—it may be inferred that this business, when conducted on a large scale, and with the requisite vigilance, is not unprofitable. In fact, the income of a piano-letting business has approached eighty thousand dollars per annum, of which one third was profit. It has, however, its risks and drawbacks. From June to September, the owner of the instruments must find storage for the greater part of his stock, and must do without most of his monthly returns. Many of those who hire pianos, too, are persons "hanging on the verge" of society, who have little respect for the property of others, and vanish to parts unknown, leaving a damaged piano behind them.

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.

Paris pianos are renowned, the world over, and consequently three tenths of all the pianos made in Paris are exported to foreign countries. France, too, owing to the cheapness of labor, can make a better cheap piano than any other country. In 1852, there were ten thousand pianos made in Paris, at an average cost of one thousand francs each; and, we are informed, a very good new upright piano can now be bought in France for one hundred dollars. But in France the average wages of piano-makers are five francs per day; in London, ten shillings; in New York, four dollars and thirty-three cents. The cream of the business, in Paris, is divided among three makers,—Erard, Hertz, and Pleyel,—each of whom has a concert-hall of his own, to give éclat to his establishment. We presume Messrs. Steinway added "Steinway Hall" to the attractions of New York from the example of their Paris friends, and soon the metropolis will boast a "Chickering Hall" as well. This is an exceedingly expensive form of advertisement. Steinway Hall cost two hundred thousand dollars, and has not yet paid the cost of warming, cleaning, and lighting it. This, however, is partly owing to the good-nature of the proprietors, who find it hard to exact the rent from a poor artist after a losing concert, and who have a constitutional difficulty about saying No, when the use of the hall is asked for a charitable object.

In Germany there are no manufactories of pianos on the scale of England, France, and the United States. A business of five pianos a week excites astonishment in a German state, and it is not uncommon there for one man to construct every part of a piano,—a work of three or four months. Mr. Steinway the elder has frequently done this in his native place, and could now do it. A great number of excellent instruments are made in Germany in the slow, patient, thorough manner of the Germans; but in the fashionable houses of Berlin and Vienna no German name is so much valued as those of the celebrated makers of Paris. In the London exhibition of 1851, Russian pianos competed for the medals, some of which attracted much attention from the excellence of their construction. Messrs. Chickering assert, that the Russians were the first to employ successfully the device of "overstringing," as it is called, by which the bass strings are stretched over the others.

The piano, then, one hundred and fifty-seven years after its invention, in spite of its great cost, has become the leading musical instrument of Christendom. England produces thirty thousand every year; the United States, twenty-five thousand; France, fifteen thousand; Germany, perhaps ten thousand; and all other countries, ten thousand; making a total of ninety thousand, or four hundred and twenty-two for every working-day. It is computed, that an average piano is the result of one hundred and twenty days' work; and, consequently, there must be at least fifty thousand men employed in the business. And it is only within a few years that the making of these noble instruments has been done on anything like the present scale. Messrs. Broadwood, of London, who have made in all one hundred and twenty-nine thousand pianos, only begin to count at the year 1780; and in the United States there were scarcely fifty pianos a year made fifty years ago.

We need scarcely say that the production of music for the piano has kept pace with the advance of the instrument. Dr. Burney mentions, in his History of Music (Vol. IV. p. 664), that when he came to London in 1744, "Handel's Harpsichord Lessons and Organ Concertos, and the two First Books of Scarletti's Lessons, were all the good music for keyed instruments at that time in the nation." We have at this moment before us the catalogue of music sold by one house in Boston, Oliver Ditson & Co. It is a closely printed volume of three hundred and sixty pages, and contains the titles of about thirty-three thousand pieces of music, designed to be performed, wholly or partly, on the piano. By far the greater number are piano music pure and simple. It is not a very rare occurrence for a new piece to have a sale of one hundred thousand copies in the United States. A composer who can produce the kind of music that pleases the greatest number, may derive a revenue from his art ten times greater than Mozart or Beethoven enjoyed in their most prosperous time. There are trifling waltzes and songs upon the list of Messrs. Ditson, which have yielded more profit than Mozart received for "Don Giovanni" and "The Magic Flute" together. We learn from the catalogue just mentioned, that the composers of music have an advantage over the authors of books, in being always able to secure a publisher for their productions. Messrs. Ditson announce that they are ready and willing to publish any piece of music by any composer on the following easy conditions: "Three dollars per page for engraving; two dollars and a half per hundred sheets of paper; and one dollar and a quarter per hundred pages for printing." At the same time they frankly notify ambitious teachers, that "not one piece in ten pays the cost of getting up, and not one in fifty proves a success."

The piano, though its recent development has been so rapid, is the growth of ages, and we can, for three thousand years or more, dimly and imperfectly trace its growth. The instrument, indeed, has found an historian,—Dr. Rimbault of London,—who has gathered the scattered notices of its progress into a handsome quarto, now accessible in some of our public libraries. It is far from our desire to make a display of cheap erudition; yet perhaps ladies who love their piano may care to spend a minute or two in learning how it came to be the splendid triumph of human ingenuity, the precious addition to the happiness of existence, which they now find it to be. "I have had my share of trouble," we heard a lady say the other day, "but my piano has kept me happy." All ladies who have had the virtue to subdue this noble instrument to their will, can say something similar of the solace and joy they daily derive from it. The Greek legend that the twang of Diana's bow suggested to Apollo the invention of the lyre, was not a mere fancy; for the first stringed instrument of which we have any trace in ancient sculpture differed from an ordinary bow only in having more than one string. A two-stringed bow was, perhaps, the first step towards the grand piano of to-day. Additional strings involved the strengthening of the bow that held them; and, accordingly, we find the Egyptian harps, discovered in the catacombs by Wilkinson, very thick and massive in the lower part of the frame, which terminated sometimes in a large and solid female head. From the two-stringed bow to these huge twelve-stringed Egyptian harps, six feet high and beautifully finished with veneer, inlaid with ivory and mother-of-pearl, no one can say how many centuries elapsed. The catgut strings of the harps of three thousand years ago are still capable of giving a musical sound. The best workmen of the present time, we are assured, could not finish a harp more exquisitely than these are finished; yet they have no mechanism for tightening or loosening the strings, and no strings except such as were furnished by the harmless, necessary cat. The Egyptian harp, with all its splendor of decoration, was a rude and barbaric instrument.

It has not been shown that Greece or Rome added one essential improvement to the stringed instruments which they derived from older nations. The Chickerings, Steinways, Erards, and Broadwoods of our day cannot lay a finger upon any part of a piano, and say that they owe it to the Greeks or to the Romans.

The Cithara of the Middle Ages was a poor thing enough, in the form of a large P, with ten strings in the oval part; but it had movable pegs, and could be easily tuned. It was, therefore, a step toward the piano of the French Exposition of 1867.

But the Psaltery was a great stride forward. This instrument was an arrangement of strings on a box. Here we have the principle of the sounding-board,—a thing of vital moment to the piano, and one upon which the utmost care is bestowed by all the great makers. Whoever first thought of stretching strings on a box may also be said to have half invented the guitar and the violin. No single subsequent thought has been so fruitful of consequences as this in the improvement of stringed instruments. The reader, of course, will not confound the psaltery of the Middle Ages with the psaltery of the Hebrews, respecting which nothing is known. The translators of the Old Testament assigned the names with which they were familiar to the musical instruments of the Jews.
