CHAPTER VI.
OF RHYME.
A rhyme must commence on an accented syllable. From the accented vowel of that syllable to the end, the two or more words intended to rhyme must be identical in sound; but the letters preceding the accented vowel must in each case be dissimilar in sound. Thus "learn," "fern," "discern," are rhymes, with the common sound of "ern" preceded by the dissimilar sounds of "l," "f," "sc." "Possess" and "recess" do not rhyme, having besides the common "ess" the similar pronunciation of the "c" and the double "s" preceding it. The letters "r" and "l," when preceded by other consonants, so as practically to form new letters, can be rhymed to the simple "r" and "l" respectively, thus "track" and "rack," "blame" and "lame," are rhymes. The same rule applies to letters preceded by "s," "smile" being a rhyme to "mile." Similarly "h" and its compound rhyme, e.g., "shows," "those," "chose," and any word ending in "phose" with "hose."
The aspirate to any but a Cockney would of course pass as constituting the needful difference at the beginning of a rhyme, as in "heart" and "art," "hair" and "air."[[15]]
In the case of "world" and "whirl'd," however, I fear common usage must compel us to declare against the rhyme, since the practice of pronouncing the "h" after "w" is daily becoming more and more uncommon.
Rhymes are single, double, or treble—or more properly one-syllabled, two-syllabled, and three-syllabled. Rhymes of four or more syllables are peculiar to burlesque or comic verse. Indeed, Dryden declared that only one-syllabled rhymes were suitable for grave subjects: but every one must have at his fingers' ends scores of proofs to the contrary, of which I will instance but one—"The Bridge of Sighs."
Monosyllables or polysyllables accented on the last syllable are "single" rhymes. Words accented on the penultimate or last syllable but one supply "double" rhymes; e.g., agita´ted, ela´ted. When the accent is thrown another syllable back, and falls on the antepenultimate as in "a´rrogate," it is in the first place a "triple" rhyme. But as in English there is a tendency to alternate the acute and grave accent, the trisyllable has practically two rhymes, a three-syllabled and a one-syllabled—thus "arrogate" and "Harrogate" rhyme, but "arrogate" may also pair off with "mate." Nevertheless it is necessary to be cautious in the use of words with this spurious accent—it is perhaps better still to avoid them. Such words as "merrily," "beautiful," "purity," ought never to be used as single-syllabled rhymes:—even such words as "merited" and "happiness" have a forced sound when so used.
Elisions should be avoided, though "bow'r" and "flow'r" may pass muster, with some others. "Ta'en," "e'er," "e'en," and such contractions may of course be used. The articles, prepositions, and such, cannot in serious verse stand as rhymes, under the same rule which condemns the separation of the adjective from its substantive in the next line.
It is scarcely necessary to premise that to write verse decently the student must have a thorough knowledge of grammar. From ignorance on that score arise naturally blemishes enough to destroy verse, as they would poetry, almost. I have seen verses which, beginning by apostrophising some one as "thou," slipped in a few lines into "yours" and "you"—or, worse still, have said "thou doeth," or "thou, who is."
Expletives and mean expressions also must be excluded. The verse should never soar to "high-falutin," or sink to commonplace language. Simplicity is not commonplace, and nobility is not "high-falutin," and they should be aimed at accordingly;—when you have acquired the one, you will as a rule find the other in its company.
When three or more lines are intended to rhyme together, the common base or accented vowel in each instance must be preceded by a different sound. For example "born," "corn," and "borne," will not serve for a triplet, because, though the first and third are both rhymes to the second, they are not rhymes to each other.
