The English Quintet is composed of any number of 5-line stanzas with the rhyme scheme ababb cdcdd, etc. The number of syllables may vary and there is no requirement for meter, though they are often written in iambic pentameter.
Here's an example.
Go, lovely Rose
by Edmund Waller
Go, lovely Rose—
Tell her that wastes her time and me,
That now she knows,
When I resemble her to thee,
How sweet and fair she seems to be.
Read the poem in its entirety.
In this example, the syllable count is 4/8/4/8/8.
So, there's your challenge for the week. I hope you'll join me in writing an English quintet. Please share a link to your poem or the poem itself in the comments.
