The idiom "change one’s tune" means to completely change your opinion or attitude about something, especially when you start to agree with someone or something you previously disagreed with.
For example, if someone was against a particular political candidate but then heard a persuasive argument in favor of that candidate, they might "change their tune" and start supporting them.
This idiom can also be used to describe a situation where someone changes their behavior or approach to a problem. For instance, if a boss was initially very strict with their employees but then realized that a more relaxed approach was better for productivity, they might "change their tune" and become more laid back.
