Another interesting fact is to be noted here—that is the analogy between sound and light, or music and painting. The difference between a sound wave and a light wave is only a difference of length. The principles underlying them are the same, and the methods by which they are produced are the same. Sound waves, to be heard, must vibrate at least as often as sixteen beats to the second. Light waves, in order to pass through the organ of vision, and reach the retina of the eye, must not vibrate at a less rate than four hundred trillions of times to the second. The difference between the eye and the ear is, one is more refined than the other. A painting is a silent piece of music, and a piece of music is an audible picture. The notes of the musical scale and the colors of the prismatic scale are analogous. The distance between C and A of the musical scale is the same as the distance between red and orange of the prismatic scale. The notes of the one scale may be translated into the colors of the other. Harmony of colors in a silk dress, would, if translated into their analogous notes, produce a piece of music that would be equally as pleasing to the ear as the colors are to the eye. Painting is only a more refined form of music. This is not fancy; it is mathematics and science. All things about us are capable of music, silent or audible. Notes belonging to some part of a great song are lodged in all created objects. Things are not measured off in continents, oceans, islands, mountains, forests, and mines only, but also in octaves. The music of the spheres is no longer a dream of the poets, but in accordance with exact science. The material system into which we are born is capable, then, not only of furnishing us food to eat and clothes to wear, but music and painting for the sense of the beautiful. A mere utilitarian, bread-and-butter philosophy does not exhaust the possibilities of even the material world. In its very construction respect to man’s higher nature was had, as well as to his lower. By so much as music and harmony of color surpass in their subtlety and refinement the coarser elements necessary to sustain the lower nature; by so much has God emphasized the value of the higher nature. Had God intended his children for no higher plane than that upon which the animals live, and no greater future for them than that which belongs to “the beasts that perish,” doubtless the beauty would have been left out. Men have been told, by one having authority, not to cast their pearls before swine. The beauty that was flung at the feet of man contained a message to a side of himself keyed to a radiant and imperishable realm.
