Here the sense, at best, is surely very vague. Probably not one auditor in a hundred, hearing an actor recite those glorious lines, attaches any intelligible meaning to the archaic word _owed’st_, the cornerstone of the whole sentence. Nevertheless, the effect is stupendous. The passage assaults and benumbs the faculties like Schubert’s “Ständchen” or the slow movement of Schumann’s Rhenish symphony; hearing it is a sensuous debauch; the man anæsthetic to it could stand unmoved before Rheims cathedral or the Hofbräuhaus at Munich. One easily recalls many other such bursts of pure music, almost meaningless but infinitely delightful—in Poe, in Swinburne, in Marlowe, even in Joaquin Miller. Two-thirds of the charm of reading Chaucer (setting aside the Rabelaisian comedy) comes out of the mere burble of the words; the meaning, to a modern, is often extremely obscure, and sometimes downright undecipherable. The whole fame of Poe, as a poet, is based upon five short poems. Of them, three are almost pure music. Their intellectual content is of the vaguest. No one would venture to reduce them to plain English. Even Poe himself always thought of them, not as statements of poetic ideas, but as simple utterances of poetic (i.e., musical) sounds. It was Sidney Lanier, himself a competent poet, who first showed the dependence of poetry upon music. He had little to say, unfortunately, about the clang-tint of words; what concerned him almost exclusively was rhythm. In “The Science of English Verse,” he showed that the charm of this rhythm could be explained in the technical terms of music—that all the old gabble about dactyls and spondees was no more than a dog Latin invented by men who were fundamentally ignorant of the thing they discussed. Lanier’s book was the first intelligent work ever published upon the nature and structure of the sensuous content of English poetry. He struck out into such new and far paths that the professors of prosody still lag behind him after forty years, quite unable to understand a poet who was also a shrewd critic and a first-rate musician. But if, so deeply concerned with rhythm, he marred his treatise by forgetting clang-tint, he marred it still more by forgetting content. Poetry that is all music is obviously relatively rare, for only a poet who is also a natural musician can write it, and natural musicians are much rarer in the world than poets. Ordinary poetry, average poetry, thus depends in part upon its ideational material, and perhaps even chiefly. It is the _idea_ expressed in a poem, and not the mellifluousness of the words used to express it, that arrests and enchants the average connoisseur. Often, indeed, he disdains this mellifluousness, and argues that the idea ought to be set forth without the customary pretty jingling, or, at most, with only the scant jingling that lies in rhythm—in brief, he wants his ideas in the altogether, and so advocates _vers libre._
