Says Mr. Gleeson White: "The taste for these _tours de force_ in the art of verse-making is no doubt an acquired one; yet to quote the first attempt to produce a lyric with a repeated burden would take one back to the earliest civilization.... Whether the first refrains were used for decorative effect only, or to give the singer time to recollect or improvise the next verse, it matters little, since the once mere adjunct was made in later French use an integral and vital part of the verse. The charm of these strictly written verses is undoubtedly increased by some knowledge of their technical rules.... To approach ideal perfection, nothing less than implicit obedience to all the rules is the first element of success; but the task is by no means finished there. Every quality that poetry demands, whether clearness of thought, elegance of expression, harmonious sound, or faultless rhythm, is needed as much in these shapes as in unfettered verse.... It may be said, without fear of exaggeration, that all the qualities required to form a perfect lyric in poetry are equally needful here, _plus_ a great many special ones the forms themselves demand. To the students of any art there is always a peculiar charm when the highest difficulties are surmounted with such ease that the consummate art is hidden to all who know not the magic password to unveil it." (_Ballades and Rondeaus_, Introduction, pp. xli, xlii.) "No one is compelled to use these complex forms, but if chosen, their laws must be obeyed to the letter if success is to be obtained. The chief pleasure they yield consists in the apparent spontaneity, which is the result of genius, if genius be indeed the art of taking infinite pains; or, if that definition is rejected, they must yet exhibit the art which conceals art, whether by intense care in every minute detail, or a happy faculty for naturally wearing these fetters." (_Ib._, pp. l, li.) A.--THE BALLADE The ballade commonly consists of three stanzas, with an envoy. In modern usage the stanzas usually contain either eight or ten lines, and the envoy half as many as the stanza; but in earlier usage both stanza and envoy varied, and the latter might be omitted altogether. The rimes in all the stanzas must be identical in the corresponding lines, but the riming words must be different. The most characteristic element is the refrain,--the keynote of the poem,--which forms the last line of each stanza, including the envoy. The favorite rime-scheme for the eight-line stanza is _ababbcbc_, with the envoy _bcbc_. Mr. White says of the envoy that it "is not only a dedication, but should be the peroration of the subject, and richer in its wording and more stately in its imagery than the preceding verses, to convey the climax of the whole matter, and avoid the suspicion that it is a mere postscript."
