The Chinese attitude toward line is almost identical with that of the French. French prosody counts every syllable as a foot, and a line is made up of so many counted feet. If any of my readers has ever read French alexandrines aloud to a Frenchman, read them as we should read English poetry, seeking to bring out the musical stress, he will remember the look of sad surprise which crept over his hearer's face. Not so was this verse constructed; not so is it to be read. The number of syllables to a line is counted, that is the secret of French classic poetry; the number of syllables is counted in Chinese. But—and we come to a divergence—this method of counting does, in French practice, often do away with the rhythm so delightful to an English ear; in Chinese, no such violence occurs, as each syllable is a word and no collection of such words can fall into a metric pulse as French words can, and, in their Chansons, are permitted to do.
The Chinese line pattern is, then, one of counted words, and these counted words are never less than three, nor more than seven, in regular verse; irregular is a different matter, as I shall explain shortly. Five and seven word lines are cut by a cæsura, which comes after the second word in a five-word line, and after the fourth in a seven-word line.
Rhyme is used exactly as we use it, at the ends of lines. Internal rhyming is common, however, in a type of poem called a "fu," which I shall deal with when I come to the particular kinds of verse.
Tone is everywhere, obviously, and is employed, not arbitrarily, but woven into a pattern of its own which again is in a more or less loose relation to rhyme. By itself, the tone-pattern alternates in a peculiar manner in each line, the last line of a stanza conforming to the order of tones in the first, the intervening lines varying methodically. I have before me a poem in which the tone-pattern is alike in lines one, four, and eight, of an eight-line stanza, as are lines two and six, and lines three and seven, while line five is the exact opposite of lines two and six. In the second stanza of the same poem, the pattern is kept, but adversely; the tones do not follow the same order, but conform in similarity of grouping. I use this example merely to show what is meant by tone-pattern. It will serve to illustrate how much diversity and richness this tone-chiming is capable of bringing to Chinese poetry.
Words which rhyme must be in the same tone in regular verse, and unrhymed lines must end on an oblique tone if the rhyme-tone is level, and vice versa. The level tone is preferred for rhyme.
In the early Chinese poetry, called Ku-shih (Old Poems), the tones were practically disregarded. But in the Lü-shih (Regulated Poems) the rules regarding them are very strict. The lü-shih are supposed to date from the beginning of the T'ang Dynasty. A lü-shih poem proper should be of eight lines, though this is often extended to sixteen, but it must be in either the five-word line, or the seven-word line, metre. The poets of the T'ang Dynasty, however, were by no means the slaves of lü-shih; they went their own way, as good poets always do, conforming when it pleased them and disregarding when they chose. It depended on the character of the poet. Tu Fu was renowned for his careful versification; Li T'ai-po, on the other hand, not infrequently rebelled and made his own rules. In his "Drinking Song," which is in seven-word lines, he suddenly dashes in two three-word lines, a proceeding which must have been greatly upsetting to the purists. It is amusing to note that his "Taking Leave of Tu Fu" is in the strictest possible form, which is at once a tribute and a poking of fun at his great friend and contemporary.
Regular poems of more than sixteen lines are called p'ai lu, and these may run to any length; Tu Fu carried them to forty, eighty, and even to two hundred lines. Another form, always translated as "short-stop," cuts the eight-line poem in two. In theory, the short-stop holds the same relation to the eight-line poem that the Japanese hokku does to the tanka, although of course it preceded the hokku by many centuries. It is supposed to suggest rather than to state, being considered as an eight-line poem with its end in the air. In suggestion, however, the later Japanese form far outdoes it.
So called "irregular verse" follows the writer's inclination within the natural limits of all Chinese prosody.
A tzŭ may be taken to mean a lyric, if we use that term, not in its dictionary sense, but as all modern poets employ it. It may vary its line length, but must keep the same variation in all the stanzas.
Perhaps the most interesting form to modern students is the fu, in which the construction is almost identical with that of "polyphonic prose." The lines are so irregular in length that the poem might be mistaken for prose, had we not a corresponding form to guide us. The rhymes appear when and where they will, in the middle of the lines or at the end, and sometimes there are two or more together. I have been told that Persia has, or had, an analogous form, and if so modern an invention as "polyphonic prose" derives, however unconsciously, from two such ancient countries as China and Persia, the fact is, at least, interesting.
