The very term “stage lighting” is not inspiring, but the art of light music will be developed and be taught in theory and practice. Masters of the art will come and men will realize that it is just as great an art to satisfy the eye with light melodies as it is to please the ear with sound melodies. There yet may be entertainments where only light music is played as there are concerts where only sound music is played. And why not? Just ask yourself the question--Why not? Of all the organs of sense the eye is the most delicate and the most wonderful. The ear responds to _air_ waves that travel at the rate of 1,100 _feet_ per second and vary in frequency from 16 to 32,000 per second. The musical notes vary from 32 to 5,000 beats per second. The eye responds to _ether_ waves that travel at the rate of 182,000 _miles_ per second and vary in frequency from 400 millions millions--the lowest red of the spectrum--to 750 millions millions (red 400,000,000,000,000; violet 750,000,000,000,000) the highest violet. * * * * * Man has devoted ages to developing harmonies in the combination of air waves, and he has reduced sound music to a science. He has devoted _all_ the ages of his being to the use of color in one way and another to please his eye, but only of late has he made any attempt to understand the _science_ of light and color music. * * * * * The _material_ civilization we _have_ attained in comparison with the _spiritual_ civilization we _should_ attain is fairly well indicated by the vast difference between the crude and natural art of _sound_ effects which is, so far, man’s most abstract achievement in art, and the incomparably finer and more ethereal art of light and color effects which will be one of the crowning achievements of man’s nobler future. * * * * * The painter of _easel_ pictures arrogates to himself the name artist and to his work the phrase _fine art_. He looks down upon the house painter, the dressmaker, and the interior decorator. Yet as compared with those who clothe our bodies and decorate our homes in harmonies of line and color the painter of easel pictures cuts very little figure in life; he plays his part but much of his inspiration is drawn from the work of the other two. It should never be forgotten that in all the great portraits of the world the clothes and the interiors that furnish the beautiful color schemes _preceded_ the pictures often by generations. The costumer and the decorator work year in and year out, from generation to generation, throughout the centuries, with not so much as a thought of the painter in the corner with his little canvas, faithfully copying. Now and then a great painter, a great sculptor, takes off his coat, turns workman for the moment and makes sculptures for buildings, paints pictures on walls, devises costumes, and contributes to making our environment more beautiful.
