Here's why:
* Rhyme: Rhyming words create a memorable auditory pattern that helps listeners retain the lines. This was especially important in a time when literacy was less widespread, and poems were often memorized and passed down orally.
* Meter: Meter refers to the rhythmical pattern of a line of poetry. Regular, predictable meters (like iambic pentameter) are easier to remember and follow. This rhythm creates a pleasing cadence that helps imprint the verses on the listener's mind.
These devices were used in various forms of poetry popular in the 14th century, such as:
* Ballad: Told stories with a simple, repetitive structure and often featured strong rhyme schemes.
* Romance: Explores chivalric tales with a more elaborate meter and rhyme structure.
* Lyric: Focused on expressing personal emotions, using rhyme and meter to create a memorable and impactful song-like quality.
While other devices like alliteration and assonance were also used, rhyme and meter were the most crucial for memorization in that era.
