What is the word called in poetry when tone makes you no feelings?

There isn't a single word in poetry that describes a tone that evokes *no* feelings. Tone, by definition, is the author's attitude towards the subject matter, which is always conveyed through a specific set of language choices. This, in turn, always evokes some kind of emotional response in the reader, even if that response is subtle or ambiguous.

However, you could describe a tone that makes you feel:

* Neutral: This suggests a lack of strong emotion or bias, like a factual report.

* Objective: Similar to neutral, but emphasizes a detached, uninvolved perspective.

* Apathetic: This implies a lack of interest or concern, suggesting the reader feels indifferent to the subject.

* Ambivalent: This describes a mixed emotional response, where the reader feels both positive and negative emotions about the subject.

* Unreadable: This describes a tone that is so subtle or complex that the reader struggles to determine the author's true feelings.

Ultimately, even a tone that aims for neutrality or apathy will likely still trigger some kind of emotional response in the reader, even if it's just a sense of boredom or disinterest.
