Rhythm denotes a thought; it is the expression of a purpose. There is will behind it; its vital part is intention, power; it is an act. Melody, on the other hand, is an almost unconscious expression of the senses; it translates feeling into sound. It is the natural outlet for sensation. In anger we raise the voice; in sadness we lower it. In talking we give expression to the emotions in sound. In a sentence in which fury alternates with sorrow, we have the limits of the melody of speech. Add to this rhythm, and the very height of expression is reached; for by it the intellect will dominate the sensuous. [01] The strength of the "Fate" motive in Beethoven's fifth symphony undoubtedly lies in the succession of the four notes at equal intervals of time. Beethoven himself marked it _So pocht das Schicksal an die Pforte_. II ORIGIN OF SONG vs. ORIGIN OF INSTRUMENTAL MUSIC Emerson characterized language as "fossil poetry," but "fossil music" would have described it even better; for as Darwin says, man _sang_ before he became human. Gerber, in his "Sprache als Kunst," describing the degeneration of sound symbols, says "the saving point of language is that the original material meanings of words have become forgotten or lost in their acquired ideal meaning." This applies with special force to the languages of China, Egypt, and India. Up to the last two centuries our written music was held in bondage, was "fossil music," so to speak. Only certain progressions of sounds were allowed, for religion controlled music. In the Middle Ages folk song was used by the Church, and a certain amount of control was exercised over it; even up to the fifteenth and sixteenth centuries the use of sharps and flats was frowned upon in church music. But gradually music began to break loose from its old chains, and in our own century we see Beethoven snap the last thread of that powerful restraint which had held it so long.
