What is Shakespeare's hero double platoon?

Heroic couplets are a kind of classical English poetic style, which evolved from ten-syllable double-rhyme poetic style. There are five steps in each line, and each step has two syllables, the first is light tone, and the second is stress. Sentence patterns are balanced, neat, accurate, concise and elegant. Heroic couplets were first created and named by john lydon, the first poet laureate, and led the English poetic style in17-18th century. There are a lot of relevant data showing that Chaucer was the first writer who widely used heroic couplets, so the heroic couplets were created by Chaucer. This answer is not comprehensive and biased. Heroic couplets are not a simple concept of rhythm, but also a concept of style and format. Chaucer did write a two-line poem, but he never wrote a heroic two-line poem. Decimal couplet was popular at that time. In Chaucer's poems, we can often see this form of kotaro oshio rhyme, but it is not a heroic couplet, but only a ten-step couplet. The development and formation of heroic couplets have gone through a long time, and they are basically stereotyped in Drayton, and the definition of heroic couplets by literary critics is also very strict. Generally speaking, the following conditions need to be met. 1, iambic pentameter 2, kotaro oshio rhyme antithesis 3, ending AA BB CC DD ... not repeated. 4. Simple style. When only a few antithetical couplets in a poem meet the above conditions, and most others do not, the poem cannot be called a heroic couplet. Just like Li Bai's long poem happens to have two seven-character quatrains, you can't say that the whole poem is a seven-character quatrain, and no one will ever call a long poem like Into the Wine a quatrain. To put it simply, Dryden's previous poems should not be called heroic duets, because he was the first writer to create this genre of poetry. Dryden's previous poems, including Chaucer's poems, should be called diploid, and poems similar in form and style to heroic diploid should be called ten-step diploid. In fact, the double-line style is the main form of English poetry, with various prosodic formats. Chaucer's era belongs to the era of letting a hundred flowers blossom. Chaucer not only wrote a diploid in ten steps, but also wrote a diploid in other steps. But Chaucer didn't write the ten-step double-line style as a genre, but as an element in poetry. Neither Chaucer nor Shakespeare has heard of the word heroic two-line style, nor do they realize that it will be the bud of a literary genre that will dominate the poetry world in the future.
