Final answer:
A sonnet is the type of poetry that expresses an individual's emotions in a structured 14-line verse, often with a musical quality.
Step-by-step explanation:
The type of poetry that expresses the thoughts and feelings of a single person, often in a very musical verse, is a sonnet. A sonnet is a poem consisting of fourteen lines with a specific rhyme scheme and structure. William Shakespeare is one of the most famous sonnet writers, and his sonnets often explore themes of love and the nature of time. Unlike other poetic forms such as haikus which focus on nature in a 5 7 5 syllable structure, or ballads which are narrative poems with a simple rhyme scheme meant to be sung, or epics that are long narrative poems discussing heroic feats, sonnets are designed to showcase a poet's dexterity with language and emotion within a tight structure that includes a volta, or turn in thought. This volta is often signaled by words like "but" or "yet".
