Change one's tune
Meaning
To alter one's opinion, attitude, or behavior, often becoming more agreeable or supportive after having been critical or resistant.
Origin
The phrase "change one's tune" is a vivid metaphor plucked directly from the world of music. Imagine a musician playing a specific melody or song; if they suddenly switch to a different one, they literally "change their tune." This simple, striking image was readily adopted into everyday language. By the 17th century, it was used to describe someone who abruptly altered their opinion, argument, or demeanor, typically shifting from a disagreeable or contrary stance to a more agreeable or convenient one. The phrase thus perfectly encapsulates a significant shift in attitude or rhetoric through a familiar musical analogy.
Examples
