"The upright piano-forte was, doubtless, taken from tho upright harpsichord, and we have always understood that it was the invention of an Englishman of the name of Hancock, a musical instrument maker resident in some part of Westminster. He was a man of much ingenuity, and produced several varieties in keyed instruments; amongst which we find the organised piano-forte, the portable grand piano-forte, and an instrument, also a pianoforte, in the shape of a spinnet. The portable grand, in its day, was a successful and desirable instrument, but has long since been superseded by instruments of the kind called kit grands, boudoir grands, pocket grands, and semi grands."

LONDON: Printed for Harrison- and Co. No. 18, Paternoster Row; and Sold by all other Booksellers, Stationers, and Newsmen, as well as at most Musick Shops, in England, Scotland, Ireland, Wales, and America.*
AND A-PIANO-FORTE, worth Twenty-five Guineas, GRATIS.  [...] WHEN the high Price of a good Piano-forte is considered, and that trie extravagant Hire of the molt mean and indifferent Instrument, is always at lead Half a Guinea or Twelve Shillings a Month, to say nothing of the prodigious and continual Expence of Musick Books, whether borrowed or bought, it is prefumed that Half a Crown a Week can never be thought a very serious Sum for the Advantage of becoming Owner of an elegant and excellent new Piano-forte, as well as a more select and compleat Library of such sterling, favourite, and fashionable Musick, as will always be esteemed valuable, than can easily be purchased at any Price.
Of the Beauty and Agreeableness of a Piano-forte, as elegant ornamental Furniture for the mod splendid Apartment, no Person can be ignorant! and even in the few genteel Families, particularly in the Country, where there may not be any convenient Opportunity of learning to play, the Pleasure and Satisfaction of possessing an Instrumemt so valuable, with Books of all the most favourite Vocal and Instrumental Pieces, ready for occasional Visitors, must be highly gratifying to every Person of Taste and Sensibility. By means of the Piano-forte Magazine, this Satisfaction will now be easily attainable, at an Expence scarcely felt by any Person in decent Life: and we may venture to suggest, that it will form a valuable and lasting, as well as a most elegant and agreeable Present, to all young Ladies, and Gentlemen, from their Parents, Relatives, or Friends, who may thus have the Pleasure of seeing them the sooner induced to undertake the Acquirement of so pleasing an Accomplishment as the enchanting Art of Musick.
Even those Ladies and Gentlemen, who already have Instruments of their own, will find this Work worthy their Attention :

LONDON - "Messrs. Harrison & Co. exhibit an upright piccolo, called the “utilitarian boudoir piano,” and made with the object of constructing a piano-forte at the least possible cost: the price of this instrument being eighteen guineas only. To effect this, several alteration shave been made. In the first place, there is only one string to each note; secondly, the keys are shorter and project less, by which the legs or scrolls usually put under the key-frame are saved ; and, thirdly, the action consists of a simple projection at the end of the key, which lifts the tail of the hammer directly, without the intervention of any hopper. It is in fact a return to the primitive single-action, with which the piano-forte was first made; the only difference being the variation in form necessary to apply it to the upright instrument. Although advocating cheapness, we cannot consider it desirable to obtain it by depriving the piano-forte of the improvements it has received, or by any other means calculated to deteriorate its quality."

LONDON - "The display of musical instruments on the British side of the building and the second shows a patent concert grand, with all the modern is very complete. Having already referred to these, however, we now merely introduce representations of two fine pianos, manufactured by   Messrs. John and James Hopkinson, of Regent Street. The first engraving is of a cottage grand, with carvings in the Italian style;  and the second shows a patent concert grand with all improvements. This is inclosed in a case- of admirable workmanship walnut, inlaid with ivory, tulip, box, and king woods, exquisitely carved. But it is not to their cases that pianos owe their chief excellence. "Without tho interior mechanism be of the liret oUfig, all the decoration in the world would render them but boxes of worthless discord. In the pianos of Messrs. Hopkinson — who has not heard them at the Exhibition discoursing "most excellent music," under the guidance of highly-educated fingers ? — the outside ornament forms but the least part of their value. True, they are fine pieces of furniture; but they possess a far higher value, for they are famous musical instruments. To hear them well played is a treat for a professor, much less a mere musical amateur like the writer. In tone, touch, and all the requisites of first-rate pianos, they are perfect — fitted alike for the concert-room or the cottage parlour — brilliant, full, and at the same time delicate, and calculated in every respect to sustain the high reputation their makers have so long had with the musical world. The valuable improvements in the manufacture of pianofortes lately introduced have all been taken advantage of by the Messrs. Hopkinson, the resources of whose establishment enable them to compete, not only in excellence, but also in economy of production, with the best makers in the trade. To go to the Exhibition on a Saturday, and to hear a fantasia on one of these instruments, is a treat indeed; and when we come to consider what a complicated piece of work is the interior of a piano — the strings stretched to a tension equal to a pressure of several tons, and yet one faulty wire putting the whole machine out of order — when we think what ingenious appliances arc necessary before these strings can answer to the light touch of a woman's finger — when we see that all the ends for which such an instrument are fully answered, and we find the English piano a highly-finished and complete box of harmony, our wonder and admiration may well be excited. To say that these instruments are as perfect as they can be made, is to say all that can be said of any piano yet manufactured: to compare them with the instruments of other eminent makers is simply futile. Among the best there can be no better." Cassell's Illustrated Exhibitor: Containing about Three Hundred, 1862, p. 208-209

"HOPKINSON'S PIANOFORTES. - Were awarded the Prize Medal in 1851, Gold Medal in 1855, and the Prize Medal in 1862. NOTICE. — By the following extract it will bo seen that, in addition to tho Medals awarded in 1862, TWO FIRMS ONLY IN GREAT BRITAIN have been selected by the Musical Jurors for Special distinction. "In making the awards for Pianofortes, the Jury have felt a difficulty arise from the Medals being all of the same value, which compels them to award apparently the same decree of honour to any merit shown by a small maker, that they would to the most successful performance of the first manufacturers in Europe. The rules established by the Commissioners do not warrant any Special awards being given; but the Jury consider they will not be exceeding their powers in placing certain makers at tho head of their list, with notices more full and special than those which follow. The makers which the Jury wish thus to distinguish are — For Great Britain, 'BROADWOOD,' and 'HOPKINSON. - HOPKINSON'S GRAND AND COTTAGE PIANOFORTES, THOUGH UNSURPASSED IN QUALITY, ARE MODERATE IN PRICE.
