The keyword phrase "september 11th song" functions as a noun phrase. In this construction, the headword is "song," which is a noun. The term "September 11th," a proper noun representing a specific date and historical event, acts as a noun adjunct or attributive noun. It modifies "song" by specifying its subject matter or context, essentially functioning as an adjective to describe a particular category of musical composition.
This grammatical determination is crucial because it establishes the article's core subject as a tangible cultural artifact: the music itself. The focus is not on the act of singing or a general feeling, but on specific, identifiable songs created in response to or associated with the September 11th attacks. This distinction directs the article's scope, requiring it to analyze, list, or discuss concrete musical works. The modifier "September 11th" sets the thematic boundary, filtering for songs whose lyrics, composition, or cultural reception are directly linked to the event. Therefore, the article's structure must be built around these specific items, such as analyzing lyrical themes, tracing the popular reception of these songs, or cataloging the various musical genres that addressed the tragedy.
Ultimately, identifying the keyword as a noun phrase clarifies that the user's intent is to find information about a collection of objects (the songs). The article must satisfy this by delivering content centered on these musical pieces as the main points of discussion. An effective article would treat each song or a thematic grouping of songs as a sub-topic, thereby aligning its content directly with the grammatical and semantic meaning of the keyword term. This foundational step ensures the article is focused, relevant, and directly addresses the subject defined by the keyword.
