You don't need to speculate, this is known as an "epithet", and is well-studied: https://en.wikipedia.org/wiki/Epithet#Literature

“Syntax is a set of principles governing the combination of discrete structural elements (words, notes) into sequences. Combinatorial principles operate at multiple levels, such as in the formation of words, phrases and sentences in language, and of chords, chord progressions and keys in music.” Patel.2003-LanguageMusicSyntax

“Syntactic knowledge allows the mind to accomplish a remarkable transformation: a linear sequence of elements is perceived in terms of hierarchical relations that convey organised patterns of meaning.”

“Syllables hierarchically arrange phonemes into words.”
