Here's why:
* Focus on emotion and personal experience: The poem primarily expresses the speaker's feelings of longing, love, and perhaps a sense of loss. This focus on emotions and subjective experiences is typical of lyric poetry.
* Musicality and imagery: O'Hara uses rich language and vivid imagery to create a sense of beauty and evoke emotional responses in the reader. This use of language and imagery is also characteristic of lyric poetry.
* No strict form or structure: While the poem uses some rhythm and rhyme, it doesn't adhere to a specific form like a sonnet or haiku. This freedom of form is another hallmark of lyric poetry.
While the poem is not explicitly labeled as a love poem, the title and themes clearly suggest that it explores the realm of romantic love. This adds another layer to its lyrical nature, making it a poignant and evocative expression of human emotion.
