_The Human Chord_, by Algernon Blackwood, is a novel based on the psychic values of sounds, which claims that sounds are all powerful, are everything,--for forms, shapes, bodies are but vibratory activities of sound made visible. The research worker here believes that he who has the power to call a thing by its proper name is master of that thing, or of that person, and that to be able to call the name of Deity would be to enable one to become as God. He seeks to bring together a human chord, four persons in harmony as to voice and soul, who can pronounce the awful name and become divine with him. He can change the form or the nature of anything by calling its name, as a woman is deformed by mispronunciation, and the walls of a room expanded by his voice. He can make of himself a dwarf or a giant at will, by different methods of speaking his own name. He says that sound could re-create or destroy the universe. He has captured sounds that strain at their leashes in his secret rooms, gigantic, wonderful. But in the effort to call upon the mighty Name he mispronounces it, bringing a terrible convulsion of nature which destroys him. The beholders see an awful fire in which Letters escape back to heaven in chariots of flame. Psychology furnishes some interesting contributions to recent fiction along the line of what might be called momentary or instantaneous plots. Ambrose Bierce's _The Occurrence at Owl Creek Bridge_ is a good example,--where a man is being hanged and in the instant between the drop from the bridge and the breaking of the neck he lives through long and dramatic adventures, escaping his pursuers by falling into the river and swimming ashore, reaching home at last to greet his wife and children. Yet in a second his lifeless body swings from the bridge. _The Warning_, by Josephine Daskam Bacon, shows the case of a man who lives years in another country during a few moments of acute mental strain carried to the point of paranoia. Barry Pain has a story where in the time in which a man drives home from the theater he visits another planet and changes the current of his life, while Algernon Blackwood compresses a great experience into a few minutes of dreaming.
