"Touching thy request for permission to play upon the monochord," begins Bembo's quaint answer, "I reply that because of thy tender years thou canst not know that playing is an art for vain and frivolous women, whereas I would that thou shouldst be the most chaste and modest maiden alive. Besides, if thou wert to play badly it would cause thee little pleasure and no little shame. Yet in order to play well thou must needs give up from ten to twelve years to the exercise, without so much as thinking of aught else. How far this would benefit thee thou canst see for thyself without my telling thee. But thy schoolmates, if they desire thee to learn to play for their pleasure, tell them thou dost not care to have them laugh at thy mortification. Therefore, content thyself with the pursuit of the sciences and the practice of needlework." These words of the poet Bembo to his daughter Elena-are they so wholly lacking in application to our own day? And I wonder-did or did not Elena learn to play the monochord? If not, it was because she lived a few centuries too soon. She would have had her own way to-day!
The Clavichord.
Monochord means "one string," and the application of the term to the instrument after other strings had been added was a misnomer. The monochord on which Elena, to the evident distress of her distinguished parent, desired to play, really was a clavichord, which was derived directly from the primitive monochord.
If you will raise the lid of your pianoforte you will find that the strings become shorter from the bass up, 41 the lowest note being sounded by the longest, the highest note by the shortest string; for the longer the string the slower the vibrations and the deeper the sounds produced, and vice versa. This principle is so obvious that it seems as if it must have been applied to the clavichord almost immediately and a separate string provided for each key. But for many years the strings of the clavichord continued all of equal length, and three or four neighboring keys struck the same string, so that the contact of the upright tangent with the string not only set the latter in vibration but also served to form the node which produced the desired note. Not until after the clavichord had been in use several centuries, were its strings made of varying length and a separate string assigned to each key. These new clavichords were called bundfrei (fret-free or tangent-free) because the node of each string was determined by that string's length and not by the contact of the tangent.
The clavichord retained the box shape of its prototype, the monochord. Originally it was portable and was set upon a table; later, however, was made, so to speak, to stand upon its own legs. In appearance it resembled our square pianofortes. It gave forth a sweet, gentle and decidedly pretty musical sound. It had a further admirable quality in its capacity for sustaining a tone, since by keeping the tangent pressed against the string the player was able to sustain the tone so long as the string continued to vibrate. Moreover, by holding down the key and at the same time making a gentle rocking motion with the finger he was able to produce a tremolo effect which German musicians 42 called Bebung (trembling), and the French balancement.
A defect of the clavichord was, however, its lack of power. This defect led to experiments which resulted in the construction of a keyboard instrument the strings of which, in response to the action of the keys, were set in vibration by jacks tipped with crow-quills or hard leather. The sound was much stronger than that of the clavichord. But the jacks twanged the strings with uniform power, "permitting a sharp outline, but no shading of the tones."
The Harpsichord.
If you chance to be listening to a Hungarian band at a restaurant you may notice that one of the players has lying on a table before him an instrument with many strings strung very much like those of the pianoforte. It is played with two little mallets in the player's hands, and produces the weird arpeggios and improvised runs characteristic of Hungarian gypsy music. It is a very old instrument called the cembalo. About the fifteenth century, it seems, some one devised a keyboard attachment with quills for this instrument, tipped the jacks with crow-quills, and called the result a clavicembalo (a cembalo with keys). This was the origin of the harpsichord, the name by which the clavicembalo soon became more generally known. 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, 43 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.
Piano and Forte.
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 44 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 45 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.
When the fingers strike the keys the hammers strike the strings, the force of the stroke depending upon the force exerted by the player, this being the distinguishing merit of the pianoforte as compared with its precursors. Under the strings are a row of dampers, and as soon as a finger releases a key the corresponding damper springs into place against the vibrating strings, stops the vibrations, and the tone ceases. Thus the tone can be dampened immediately by raising the finger or prolonged by keeping the finger pressed down on the key. This is the device which enables the pianist to play staccato or legato. The damper pedal, or loud pedal, checks the action of all the dampers and prolongs the tones even after the fingers have released the keys. The soft pedal brings the hammers nearer the strings, shortens the stroke and produces a softer tone. The simultaneous use of both pedals is a modern 46 virtuoso effect and a very charming one, for the damper pedal prolongs the gentle tones produced by the use of the soft pedal. I believe Paderewski was the first of the great pianists who have visited this country, to...
