they think of it in its associations with poetry, religious and patriotic observances, moral and legal precepts, historic relations, etc. Music, on its vocal side, was mere emphasized speech inflection; it was a slave to poetry; it had no rhythmical laws of its own. The melody did not convey aesthetic charm in itself alone, but simply heightened the sensuous effect of measured speech and vivified the thought. Mr. Spencer’s well-known expression that “cadence is the comment of the emotion upon the propositions of the intellect” would apply very accurately to the musical theories of the ancients. Certain modes (that is, keys), on account of convenience of pitch, were employed for certain kinds of poetical expression; and as a poem was always chanted in the mode that was first assigned to it, particular classes of ideas would come to be identified with particular modes. Associations of race character would lead to similar interpretation. The Dorian mode would seem to partake of the sternness and vigor of the warlike Dorian Spartans; the Lydian mode and its melodies would hint of Lydian effeminacy.[9] Instrumental music also was equally restricted to definite meanings through association. It was an accompaniment to poetry, bound up with the symbolic dance, subordinated to formal social observances; it produced not the artistic effect of melody, harmony, and form, but the nervous stimulation of crude unorganized tone, acting upon recipients who had never learned to consider music as anything but a direct emotional excitant or an intensifier of previously conceived ideas.
