All sounds, and more than all, silence, do fife and drum for us.[92] The least creaking doth whet all our senses and emit a tremulous light, like the aurora borealis, over things. As polishing expresses the vein in marble and the grain in wood, so music brings out what of heroic lurks anywhere.[93] * * * * * To the sensitive soul, the universe has its own fixed measure, which is its measure also, and, as a regular pulse is inseparable from a healthy body, so is its healthiness dependent on the regularity of its rhythm. In all sounds the soul recognizes its own rhythm, and seeks to express its sympathy by a correspondent movement of the limbs. When the body marches to the measure of the soul, then is true courage and invincible strength.[94] * * * * * The coward would reduce this thrilling sphere music to a universal wail, this melodious chant to a nasal cant. He thinks to conciliate all hostile influences by compelling his neighborhood into a partial concord with himself, but his music is no better than a jingle which is akin to a jar,—jars regularly recurring.[95] He blows a feeble blast of slender melody, because nature can have no more sympathy with such a soul than it has of cheerful melody in itself. Hence hears he no accordant note in the universe, and is a coward, or consciously outcast and deserted man. But the brave man, without drum or trumpet, compels concord everywhere by the universality and tunefulness of his soul.[96] "Take a metallic plate," says Coleridge, "and strew sand on it; sound a harmonic chord over the sand, and the grains will whirl about in circles, and other geometrical figures, all, as it were, depending on some point relatively at rest. Sound a discord, and every grain will whisk about without any order at all, in no figures, and with no points of rest." The brave man is such a point of relative rest, over which the soul sounds ever a harmonic chord. * * * * * Music is either a sedative or a tonic to the soul.[97] I read that "Plato thinks the gods never gave men music, the science of melody and harmony, for mere delectation or to tickle the ear; but that the discordant parts of the circulations and beauteous fabric of the soul, and that of it that roves about the body, and many times, for want of tune and air, breaks forth into many extravagances and excesses, might be sweetly recalled and artfully wound up to their former consent and agreement."[98] * * * * * By dint of wind and stringed instruments the coward endeavors to put the best face on the matter,—whistles to keep his courage up. * * * * * There are some brave traits related by Plutarch; e. g.: "Homer acquaints us how Ajax, being to engage in a single combat with Hector, bade the Grecians pray to the gods for him; and while they were at their devotions, he was putting on his armor."
