Like the practical “schools,” the theoretical have also become innumerable. I take as a few of the most important works the following: Adolph Kullak’s “Aesthetic of Piano-playing,” re-edited by Bischoff, a unique and profound work on the theory of the art, as a hundred years’ experience and the careful observations of the author have enlarged it; Hugo Riemann’s “Comparative Theoretical and Practical Piano School, presenting system, method, and materials, in a historic and organic connection”; and, among the innumerable “schools” and volumes of exercises, the various thoughtful works of Germer. Two main principles have come to occupy the first place in the newest school-practice. First, the systematic carrying out—not merely of a musical mechanic of the hand, but its thorough gymnastic. This was the natural advance, which carried yet further the teaching of Czerny. The hand is adapted for piano-playing—as in the systems of Thilo, Virgil, and others—by gymnastics of the fingers, and stretching of the muscles. Thus a great part of the gymnastic cultivation is got over before actual musical practice begins. In this work the dumb keyboards, which to-day are constructed with great delicacy, have borne a great part. They now admit of legato playing and of different degrees of strength in touch.

The second great principle is to take into account in instruction the peculiarities of the pupil’s hand. It stands to reason that the same exercises will not do for all hands. One hand demands this, the other that. This method is carried out with the utmost precision by the greatest of teachers, Leschetizky. A similar principle prevails in modern teaching of singing. We no longer endeavour to base voice-cultivation on the universal vowel A, but on that vowel which comes most natural to the organ of the pupil.

The arrangement of the keys is the sacred tradition of centuries. It presents the tone-system, as it were, lengthways, and is the natural expression of a melodic musical concept. The separation of the black and the white keys has been introduced in accordance with a certain theoretical principle, which allows the difference of position in our scales over the black and white keys to appear somewhat complicated. Our keyboards are constructed entirely on the C major scale; the tones outside this scale are thrown into the black keys, and thus appear in a subordinate position: thus all other scales have a strange form and often a somewhat difficult fingering. But since the seventeenth century our conception of music has gradually, from melodic, become harmonic; we hear vertically as well as horizontally; we hear the beauty of all chords as sounded together, and, unconsciously, we fill in the harmonies to every melody we hear. It would have been natural if the keyed instruments had adapted themselves to this altered musical conception, and had resigned the original conception of the scale to make way for harmonic conveniences. Nothing, however, is slower to be reached than the determination to revolutionise from the foundation a technique adopted in the schools, since no one is willing to make the sudden break with the old and the sudden start with the new.

Attempts had already been made to break the monopoly of the C major scale, and to form a regular chromatic scale of twelve similar keys. In our own day Paul von Janko has improved this system by repeating every regular chromatic series three times in terrace-style one above another, so that not only wider stretches, but also, without much movement of the hand, a surprising control of full chords and of rapid passages is attained. The tones are thus brought more narrowly together as the monopoly of the C major key is destroyed; and the result betokens a decisive advance in the conception of modern music. This conception still embodies a compromise between the old scale-keyboard and an arrangement of the keys, which, founded on harmonic ideas, has promise for the future. Janko’s keyboard is slowly gaining converts. Great houses, like those of Ibach, Duysen, Kaps, and Blüthner, are taking it up. Hausmann in Berlin, and Wendling in Leipzig, are the chief supporters of the scheme. In America we hear stories of remarkable results. Only by the development of such a new keyboard, which will have to answer the demands of the modern conception of music, will it be possible to draw new tone-effects from the piano. Its utmost capacities, in its present form, have been exhausted, it would seem, by Liszt.

Meanwhile the construction of the instruments has advanced to an unexampled perfection. It is only a hundred years since Stein began his laborious attempts on the new pianoforte. To-day a network of factories is spread over the whole world, in which innumerable faultless instruments are made, which put to use all the results of experience in the treatment of wood and wires. The modern pianos have already attained so completely the ideal of the hammer-mechanism that we are beginning to hark back to the forgotten tones of the cembalo. In Paris these aims have their strongest support in Diémer, who plays his Couperin on clavecins, and at the same time wins new renown for the oboe d’amour and the viol da gamba in the chamber-concert. Already quill-claviers are being more frequently constructed, and the reaction against the predominance of the pianoforte finds its satisfaction in their sweet and thrilling sounds.

It is impossible to review all the piano-factories of both hemispheres, or to register all their innovations. I must content myself with mentioning the system of “overstringing,” invented simultaneously by several persons; the felting of the hammers, introduced by Pape; the third pedal of Steinway which holds on single tones without affecting the others; the use of a cast-iron frame and of cast-steel strings; and the vertical stringing of the upright “cottage” piano, which is developed out of older forms. Bechstein’s factory in Berlin stands at the head of German manufacture; but there are also Duysen, Blüthner, Schiedmayer, Irmler, Westermayer, Kaps, Ibach, and innumerable others; Bösendorfer in Vienna, Knabe in Baltimore, and Steinway in New York, who have succeeded to the renown of Chickering; besides the many other older-established firms. Bechstein, so fundamentally sound; and Steinway, with his patent fulness of tone, are the two rivals for the laurel at the end of the century.

Henry Engelhard Steinway, born in Brunswick, began, in the fifties, his New York business in very small circumstances. A three-storied house was the factory, and one piano a week was the output. In 1859, however, the firm was in a position to build a great establishment, which now, after several enlargements, covers more than four acres. The output advanced with giant strides: numerous patents were taken out for the improvement of the resonance and the fulness of tone: in 1872 the Emperor Alexander bought the twenty-five thousandth piano, and in 1883 Baron Nathaniel de Rothschild of Vienna bought the fifty thousandth. Besides the factory, the firm possesses in Astoria great estates, the timber of which covers not less than a hundred and fifty acres. There they have their yards, saw-mills, turning-mills, foundries, metal-workshops, and mechanical wood-bending and carving apparatus. The parts are sent from Astoria to New York to be fitted together. When completed, the pianos are exhibited in Steinway Hall (14th Street) with a view to sale. More than ninety thousand have been completed up to date, of which a large proportion has been transmitted to Europe through the London and Hamburg branches.
