The metrical poems in many European languages, including English, mostly originated in Italy, and the sonnet is undoubtedly the most famous one. Sonnets were originally a kind of "stanza" (paragraphs with the same format forming a long poem), but in Italy, France and Britain, they have long been used to write independent lyric poems. A strict sonnet consists of eight stanzas and six stanzas, each of which is iambic and pentameter. It should be noted that English poems learned from Italy also have a section called "terza rima", each section has 12 lines, and Dante's Divine Comedy was written with it. The main part of Shelley's five ode to the west wind poems is also written in this verse, and then ends with antithesis, so that each poem has 14 lines. The rhyming form of the three-rhyme poem is "aba bcb cdc ded", which is the case with Shelley's first poem "ode to the west wind". It is not difficult for readers to see that this is a "cycle" of three lines, and there is a sequential relationship between them. Because of the alternate use of different sounds, the whole poem appears regular and varied, not rigid.
The end of each sentence (or chapter) seems to be the "summary" of the first sentence in meaning, but it is also a self-contained unit in meter. Dui is the simplest verse, with only two lines of the same or similar ending rhyme, and usually it is not a poem alone. Among the famous British poets, only alexander pope (1688- 1744) in the 8th century wrote this antithetical poem with only two lines, which was concise and often cited as an epigram.
This Italian sonnet is divided into two sections, with eight before six. The first eight rhymes are abba, abba. There are two kinds of the last six sentences, cdecde,
Or cdccdc. The ninth sentence is not only a rhyme card, but also a different topic or feeling.
