Final answer:
End rhyme is when the final syllables of poem or song lines rhyme; couplets are pairs of rhyming lines. Different stanzaic forms like quatrains and tercets have unique rhyme schemes. Ballads, often sung, traditionally use an ABCB rhyme scheme.
Step-by-step explanation:
The end rhyme is the pattern where the last syllables of the lines in a poem or a song rhyme. It is the most common form of rhyme used in poetry. When analyzing a poem's rhyme scheme, we assign a letter to each end rhyme. Lines that rhyme with each other are given the same letter. For instance, in a quatrain with an AABB rhyme scheme, the first and second lines end with sounds that rhyme, as do the third and fourth. The couplet is a pair of end-rhyming verse lines, which is a prominent feature in many poems, including those by Shakespeare. As observed in some structured poems, indentations may also indicate lines that rhyme with each other. Furthermore, there are various stanzaic forms like the quatrain and the tercet, which have their own specific rhyme schemes such as ABAB, ABBA, AABA, and ABCB.
Additionally, the ballad is a type of poem that often uses the ABCB rhyme scheme. Ballads typically combine a rhythmic pattern with this rhyme scheme, and were traditionally sung to musical accompaniment. The combination of rhyme and rhythm makes the language of poems memorable and impactful to the listener or reader.
