When someone is said to "harp on one string," it suggests that they are excessively fixated on a particular subject, often to the point of annoyance or tediousness. This idiom has a negative connotation as it implies a lack of variety or flexibility in one's thinking or conversation.

The idiom is widely recognized and understood by native English speakers across different regions and generations.

"Harp on one string" is a vivid metaphor that conjures images of a musician continuously playing the same note on a harp, without any variation or deviation.
