Copla Real, popular in 15th century Spain, is a decastich which is made up of 2 Quintillas.
The Copla Real is:
○ a decastich (10 line poem) made up of 2 Quintillas (Spanish 8 syllable line quintains turned on only 2 rhymes of any combination other than never ending with a rhymed couplet.)
○ syllabic, all lines are 8 syllables.
○ rhymed, the rhyme scheme established in the first quintain is repeated in the 2nd quintilla. Possible rhyme schemes ababa, abbab, abaab, aabab, or aabba. The one no-no is it should never end in a rhyming couplet.
