It would be difficult to overestimate the debt that music owes to the pianoforte. Including for the present under this one name the various keyboard instruments from which it was developed, the sonata form had its first tentative beginnings upon it and was wrought out to perfection through it by a process of gradual evolution extending from Domenico Scarlatti through Bach’s son, Philipp Emanuel Bach, to Beethoven. As a symphony simply is a sonata for orchestra, 36 it follows that through the sonata and thus through the pianoforte the form in which the classical composers cast their greatest works was established. Richard Strauss, in his revision of Berlioz’s book on orchestration, even goes so far as to assert that Beethoven, and after him Schumann and Brahms, treated the orchestra pianistically; but the discussion of this point is better deferred until we take up the orchestra and orchestral music.
Here, however, it may be observed that in addition to its constant use as an instrument for the concert hall and the home, and for the delight of great audiences and the joy of the amateur player and his familiar circle, many of the great composers, even when writing orchestral works, have used the pianoforte for their first sketches, testing their harmonies on it, and often, no doubt, while groping over the keys in search of the psychical note, hit upon accidental improvements and new harmonies. Even Wagner, who understood the orchestra as none other ever has, employed the pianoforte in sketching out his ideas. “I went to my Erard and wrote out the passage as rapidly as if I had it by heart,” he writes from Venice to Mathilde Wesendonck, in relating to her the genesis of the great love duet in “Tristan und Isolde,” and I could quote other passages from my “Wagner and his Isolde,” which is based on the romantic passages in the lives of the composer and the woman who inspired his great music-drama, to show the frequency with which he made similar use of the universal musical instrument.
The pianoforte has in many other ways been a boon to some of the most famous composers. Many of them 37 were pianists, and by public performances of their own works materially accelerated the appreciation of their music. Mozart was a youthful prodigy, and later a virtuoso of the highest rank. Beethoven, before he was overtaken by deafness, introduced his own pianoforte compositions to the public and was the musical lion of the Viennese drawing-rooms. Mendelssohn was a pianist of the same smooth, affable, gentlemanly type as his music. Chopin was not a miscellaneous concert player—his nature was too shrinking; but at the Salon Pleyel in Paris he gave recitals to the musical élite, who in turn conveyed his ideas to the greater public. Schumann began his musical career as a virtuoso, but strained the fourth finger of his right hand in using a mechanical apparatus which he had devised for facilitating the practice of finger exercises. His wife, Clara Wieck, however, who was the most famous woman pianist of her time, substituted her fingers for his. Liszt literally hewed out the way for his works on the keyboard. Brahms was a pianist of solid, scholarly attainments. In fact, dig where you will in musical soil, you strike the roots of the pianoforte.
Its Lowly Origin.
It must not be supposed, however, that the instrument as we know it attained to its present supremacy except through a long process of evolution. One of the immediate precursors of the modern pianoforte was the harpsichord, a name suggesting that the instrument was a harp with a keyboard attachment, and such, in a general way, the pianoforte is. But the harp is 38 a very fully developed affair compared with the mean little apparatus in which lay and was discovered many centuries ago the first germ of the king among instruments. This was the monochord, and it has required about nine centuries for the evolution of an instrument consisting of a single string set in vibration by means of a keyboard attachment into the modern pianoforte. But do not be alarmed. I am not about to give a nine hundred years’ history of the pianoforte. Such detailed consideration would belong to a technical work on the manufacture of the instrument and would be out of place here. Something of its history should, however, be known to every one who wants to understand music, but I shall endeavor to be as brief and at the same time as clear as possible.
The monochord originally was used much as we use a tuning fork, to determine true musical pitch. If you take a short piece of string, tie one end of it fast, draw it taut and pluck it, its vibrations will sound a note. If you grasp the string and draw it taut from nearer to the point where it is tied, you shorten what is called the “node,” increase the number of vibrations and produce a higher note. The monochord in its simplest form consisted of a string drawn taut over an oblong box and tuned to a given pitch by means of a peg. Under the string and in contact with it was a bridge or fret that could be moved by hand along a graduated scale marked on the bottom of the box. By moving the bridge the node of the string could be shortened and the notes marked at corresponding points on the graduated scale produced. After a while, and in order to facilitate the study of the harmonious relationship between 39 different notes, three strings were added, each with its bridge and graduated scale.
It was more or less of a nuisance, however, to continually shift four bridges to as many different points under the four strings. As an improvement upon this awkward arrangement some clever person conceived about the beginning of the tenth century, the idea of borrowing the keyboard from the organ and attaching it to the monochord. To the rear end of each key was attached an upright piece called a tangent. When the finger pressed upon a key the tangent struck one of the strings, set it in vibration, and at the same time, by contact, created a node which lasted as long as the key was kept down and the tangent remained pressed against the string. To increase the utility of the instrument by adding more strings and more keys was the next obvious step, and gradually the monochord ceased to be a mere technical apparatus for the determining of pitch and became an instrument on which professionals and amateurs could play with pleasure to themselves and others.
A Poet’s Advice to His Musical Daughter.
There has been preserved to us from about the year 1529 a reply made by the poet Pietro Bembo to his daughter Elena, who had written to him from the convent where she was being educated asking if she could have lessons upon the monochord, which seems to have been as popular in its day as its fully developed successor, the modern pianoforte, is now.
