change your tune

Syllable breakdown

Dictionary meaning

to alter one's opinion, attitude, or stated position, especially when that change is prompted by a change in circumstances rather than by genuine persuasion; the phrase often implies that the shift is self-serving — that the person has changed their tune because it has become advantageous or necessary to do so, not because they have genuinely reconsidered their views; occasionally used without this critical edge to describe any significant shift in perspective or stance, but the musical metaphor of changing from one song to another captures the sense of a deliberate departure from a previously maintained position
