Schumann had discovered the superiority of the mental method of composing from experience. In a letter dated 1838 he writes concerning his "Davidstänze:" "If I ever was happy at the piano it was when I composed these pieces;" and it was well known that up to 1839 "he used to compose sitting at the instrument." We have also just seen how Beethoven practically composed one of his "Fidelio" arias at the piano. Nor was this by any means an isolated instance. To cite only one more case: Ries relates that one afternoon he took a walk with Beethoven, returning at eight o'clock. "While we were walking," he continues, "Beethoven had constantly hummed, or almost howled, up and down the scale, without singing definite notes. When I asked him what it was, he replied that a theme for the last allegro of the sonata had come into his head. As soon as we entered the room, he ran to the piano, without taking off his hat. I sat down in a corner, and he had soon forgotten me. For at least an hour he now improvised impetuously on the new and beautiful finale of the sonata [opus 57]." Another of Beethoven's contemporaries, J. Russell, has left us a vivid description of Beethoven when thus composing at the piano, or improvising: "At first he only struck a few short detached chords, as if he were afraid of being caught doing something foolish; but he soon forgot his surroundings, and for about half an hour lost himself in an improvisation, the style of which was exceedingly varied, and especially distinguished by sudden transitions. The amateurs were transported, and to the uninitiated it was interesting to observe how his inspirations were reflected in his countenance. He revelled rather in bold, stormy moods than in soft and gentle ones. The muscles of his face swelled, his veins were distended, his eyes rolled wildly, his mouth trembled convulsively, and he had the appearance of an enchanter mastered by the spirit he had himself conjured."
Russell was probably one of the witnesses of whom Richard Wagner remarked, in his essay on Beethoven, that they have testified to the incomparable impression which Beethoven made by his improvisations at the piano. And Wagner adds the following suggestive words: "The regrets that there was no way of writing down and preserving these instantaneous creations cannot be regarded as unreasonable, even in comparing these improvisations with the master's greatest works, if we bear in mind the fact, taught by experience, that even less gifted musicians, whose written compositions are not free from stiffness and inelegance, sometimes positively amaze us by the quite unexpected and fertile inventiveness which they display while improvising."
A similar remark was made by De Quincey, in pointing out the spontaneous origin of some of his essays: "Performers on the organ," he says, "so far from finding their own impromptu displays to fall below the more careful and premeditated efforts, on the contrary have oftentimes deep reason to mourn over the escape of inspirations and ideas born from the momentary fervors of inspiration, but fugitive and irrevocable as the pulses in their own flying fingers."
By way of illustrating this thesis a few more cases may be cited. Mozart used to sit up late at night, improvising for hours at the piano, and, according to one witness, "these were the true hours of creation of his divine melodies," a statement which, however, we shall presently see reason to modify somewhat. Schubert never improvised in public like Mozart, but only "in the intervals of throwing on his clothes, or at other times when the music within was too strong to be resisted," as Mr. Grove remarks. What an inestimable privilege it must have been to witness the spontaneous overflow of so rich a genius as Schubert! And once more, Max Maria von Weber writes that his father's improvisations on the piano were like delightful dreams. "All who had the good fortune to hear him," he says, "testify that the impression of his playing was like an Elysian frenzy, which elevates a man above his sphere and makes him marvel at the glories of his own soul."
In reading such enthusiastic descriptions—and musical biographies are full of them—we cannot but echo De Quincey and Wagner in regretting that there has been no shorthand method of taking down and preserving these wonderful improvisations of the great masters. Future generations will be more favored, if Mr. Edison's improved phonograph fulfils the promises made of it. For by simply placing one of these instruments near the piano it will be possible hereafter to preserve every note and every accent and shade of expression, and reproduce it subsequently at will. And not only will momentary inspirations be thus preserved, but musicians will no longer be compelled to do all the manual labor of writing down their compositions, but will be able to follow the example of those German professors, who when they wish to write a book, simply engage a stenographer to take down their lectures, which they then revise and forward to the publisher. True, the orchestration will always have to be done by the master's own hands, but in other respects musicians of the future will be as greatly benefited as men of letters by the new phonograph which, it is predicted, will create as great a revolution in social affairs as the telegraph and railroad did when first introduced.
The charm of improvisation lies, of course, in this, that we hear a composer creating and playing at the same time. This very fact, however, ought to make us cautious not to overestimate the value of such improvisations. For we all know how a great genius can invest even a commonplace idea with charm by his manner of expressing or rendering it. It is probable, therefore, that in most cases these improvisations, if noted down and played by others, would not make as deep an impression as the regularly written compositions of the great masters. It is with music as with literature. Schopenhauer says that there are three classes of writers: The first class, which is very numerous, never think at all, but simply reproduce echoes of what they have read in books. The second class, somewhat less numerous, think only while they are writing. But the third class, which is very small, only write after thinking and because their thoughts clamor for utterance.
If we apply this classification to music we see at once that improvising comes under the second head: improvising is thinking or composing while playing. But the greatest musical ideas are those which are conceived entirely in the mind, which needs no pen or piano mechanically to stimulate its creative power. Of this there can be no question, whatever. With an almost absolute unanimity we find that the greatest composers conceived their immortal ideas in the open air, where there was no possibility of coaxing them out of an instrument. And not only is the bare outline thus composed mentally, but the whole composition with all its involved harmonies and varied orchestral colors is present in the composer's mind before he puts it down on paper. The composition of "Der Freischütz" affords a remarkable confirmation of this statement. Weber began to compose this opera mentally on February 23, but did not write down a single note before the second of July. That is, he kept the full score of this wonderful work in his brain for more than four months, and, as his son remarks, "there is not a number in it which he did not work over ten times in his mind, until it sounded satisfactory and he could say to himself 'That's it,' and then he wrote it down rapidly without hesitation and almost without altering a note."
This power of elaborating a musical score in the mind, and hearing it inwardly, is a gift which unmusical people find it difficult to comprehend, and which even puzzles many musical people. Yet it is a power which all students of music ought to possess; and, like other capacities, it can be easily cultivated and strengthened.
A comparison with two other senses will throw some light on the matter. Most of us can, by thinking fixedly of some appetizing dish, recall its flavor sufficiently to start a nerve current and stimulate the salivary glands. The image of the flavor, so to speak, makes the mouth water. What do we do when we go to a restaurant and look over the bill of fare? We simply, on reading the list, recall a faint gastronomic image, as it were, of each dish, and the one which is most vivid, owing to the peculiar direction of the appetite, decides our choice.
The sense of sight presents many curious analogies. Mr. Galton, in his "Inquiries into Human Faculty," gives the results of a series of investigations which show that there are great differences among persons of distinction in various kinds of intellectual work in the power of recalling to the mind's eye clear and distinct images of what they have seen. Some, for instance, in thinking of the breakfast table, could see all the objects—knives, plates, dishes, etc., in the mental picture as bright as in the actual scene, and in the appropriate colors; others could recall only very dim or blurred images of the scene, or none at all; and all stages, from the highest to the lowest visualizing power, were represented in the letters he received on the subject.
