How to Appreciate Music — Reading Companion

Harpsichords were shaped somewhat like our grand pianofortes, but were much smaller. A spinet was a small harpsichord, and the virginal a still smaller one. Sometimes, indeed, virginals were made no larger than workboxes, the instrument being taken out of the box and placed on a table before the player.

For the purposes of this book this very general survey of the precursors of the pianoforte seems sufficient. The clavichord and the instruments of the harpsichord (harpsichord, spinet, and virginal) class flourished alongside of each other, but the best musicians gave the preference to the clavichord because of its sweet tone and the delicately tremulous effect that could be produced upon it by the _balancement_. Experiments in pianoforte making were in progress already in Bach's day, but he clung to the clavichord, as did his son, Philipp Emanuel Bach. Mozart was the first of the great masters to realize the value of the pianoforte and to aid materially in making it popular by using it for his public performances. And yet even then the clavichord, "that lonely, melancholy, unspeakably sweet instrument," was not abandoned without lingering regret by the older musicians, and it still was to be found in occasional use as late as the beginning of the last century. How thoroughly modern the pianoforte is will be appreciated when it is said that a celebrated firm of English makers founded in 1730 did not begin to manufacture pianofortes until 1780 and continued the production of clavichords until 1793.

Neither on the clavichord nor on the harpsichord could the player vary the strength of the tone which he produced, by the degree of force with which he struck the keys. Swells and pedals worked by the knees and the feet were devised to overcome this difficulty, but "touch" as we understand it to-day was impossible with the instruments in which the degree of sound to be produced was not under the control of the player's fingers. The clavichord was _piano_, the harpsichord was _forte_. Not until the invention of the hammer action, the substitution of hammers for tangents and quill-jacks, was an instrument possible in which whether the tone should be _piano_ or _forte_ depended upon the degree of strength with which the player struck the keys. This instrument was the first pianoforte. It was invented and so named in 1711 by Bartolomeo Cristofori, of Florence, and, although nearly two centuries have elapsed since then, the action used by many pianoforte manufacturers of to-day is in its essentials the same as that devised by this clever Italian. The invention frequently is ascribed to Gottfried Silbermann, a German (1683-1753). But the real situation is that Cristofori was the inventor, while Silbermann was the first successful manufacturer of the new instruments, from a business point of view. Time and improvements were required before they made their way, and how slow many professional musicians were in giving up the beloved clavichord for the pianoforte already has been pointed out. But the latter was bound to triumph in the end.

I shall not attempt to give a technical description of the mechanism of the pianoforte. But I should like to answer a few questions which may have suggested themselves to players who may not have cared to take their instruments apart and examine them, or have not been present when their tuners have taken off the lid and exposed the strings and mechanism to view. The strings of the pianoforte are of steel wire, and their tension varies from twelve tons to nearly twenty. Those of the deepest bass are covered with copper wire. Eight or ten tones of the bass are produced by the vibration of these copper-wound strings. Above these, for about an octave and a half, the strings are in pairs, so that, the hammer striking them, there are two unison strings to a tone, simultaneously, and producing approximately twice as powerful a tone as if only one string had been set in vibration. The five remaining octaves have three strings to a tone.

All Depends on the Player.
