Lyricalness refers to the quality of being poetic or musical in language, but its antonyms refer to the lack of this quality. The opposite of lyricalness can be described as prosaic, mundane, or unpoetic. It denotes a style of writing that lacks the musical and emotional qualities that one usually associates with lyricalness. Stilted, awkward, and clumsy are other antonyms of lyricalness, indicating a lack of flow, rhythm, and grace in writing. Finally, we can also use dull, monotonous, and bland as synonyms of unlyricalness, indicating writing that is plain, unremarkable, and lacking in imagination.
