Quick answer: “Change Your Tune” means change your opinion or behaviour completely, often due to new circumstances.
Change your tune — to change one's opinion, attitude, or behaviour, often because of new circumstances or after realising one was wrong.
Origin & History
The idiom draws on a musical metaphor — a "tune" represents a person's expressed viewpoint or way of behaving, just as a musical tune has a specific character. To "change your tune" is to switch to a different melody, i.e. a different position or attitude. The phrase has been in use in English since at least the 16th century, when it appeared in moral literature meaning to change one's tone of speaking.
Over time, the idiom evolved to describe any significant change in position, especially one that is prompted by new information, social pressure, or personal circumstances. It is often used with a note of surprise or mild criticism — implying the person's earlier position was wrong or stubborn. Idioms like this are the kind of expression documented in general reference works such as the Cambridge Dictionary, which record how figurative meanings develop in everyday English.
