Quatrains

A basic four-line form is the quatrains

With length of four or five metrical feet

With rhyming scheme A, B, A, B again

Like the one in this verse your eyes just meet

A variant of the four-line quatrain

With length of four or five metrical feet

Drop like tears one rhyme with A, B, C, B

Like the one in this verse your eyes just meet

Another variant of the quatrain

With length of four or five metrical feet

Like the one after these lines your eyes meet

With the rhyming scheme A, B, B, A again

And variants that do not rhyme at all

Not repetitive as a vibration

Not dropping like raindrops from the dark sky

Not clustered and separating its rhyme
