The composer, having articulated his form, clothes it in such melodic and harmonic material, moulded into such shape, as will realize his fancy's ideal. The outcome of exhaustive knowledge, directed with justifiable freedom, is musical symmetry.
The next attribute is, as in the case of the rose, color; which in music is more or less attractive according to the richness of the material applied and the artistic skill and care bestowed upon its arrangement.
There are several sources to which the tone painter may resort for what might be termed primary colors,—viz., the human voice, the characteristic qualities of instruments, harmonic compounds, and rhythm, the combining and blending of these primary colors so as to produce the most effective shade for each episode, not only when considered by itself, but also in its relations to the whole panoramic succession of the finished picture, is the problem that so few solve. Most composers seem to feel quite satisfied if they succeed in startling us with uncommon combinations, however crude and irrelevant.
Next comes sentiment, which is to music what fragrance is to the rose, and what intellectuality is to woman. All three would be hollow mockeries without this parallel endowment. A piece of music must express a human desire, a belief, or an emotion, otherwise it is but empty sound.
These three attributes—symmetry, color, and sentiment—are at the command of all talented musicians, but the all-pervading individuality that so adjusts form, so arranges color, and gives such adequate expression to each shade of feeling as to create natural but unique tone pictures, is possessed by few composers of any given generation.
So-called original music may be nothing more than the fruit of good taste displayed in the arrangement of laboriously sought peculiarities of means and modes, and it is therefore only outwardly individual; but music whose themes spring from a pronounced individual feeling, which feeling moulds its form and makes each contributive detail conform to the spirit of the initial impulse, is truly original. Individual music is then radically original, but original music is not necessarily individual.
A spark of individual genius, because of its clean brilliancy, sends out its rays into illimitable space; whereas a whole bonfire of purposeful eccentricities curtains its flames with non-radiating elements, illuminating but a small field.
Now we must step backward beyond that point where science begins to shed her light upon natural laws. What agency produces life, starts and keeps in motion the machinery of our bodies, and places a soul behind our features? The same agency must guide us in the conception of musical ideas, or they will lack all living elements. This power is God: God in us,—a well-spring of inspiration for those whose susceptibilities are sufficiently acute to feel its influence.
Science can teach us to produce rich harmonic successions and instrumental colors, but it cannot impart the magical power of spontaneous and sequential growth that characterizes great compositions, nor can it show us how to identify the spirit which pervades such works. Any one can prepare himself to weigh the intellectual properties of a musical work, but the spirit which these properties are supposed to clothe will not materialize for unsympathetic souls. Herein exists the reason for differences of opinion entertained by cultured and honest critics.
Some works possessing all the attributes of greatness must be often heard before they begin to enlist our sympathies. Others, equally inspired, fail to awaken responsiveness in certain persons. Differently constituted natures cannot be expected to vibrate in unison, and as real music is soul vibration made audible, it seeks responsiveness in our natures, as any given tone lays hold of objects whose vibrations are sympathetic, causing them to emit consonant sounds.
