The phrase "called the tune" is typically used to describe someone who is in control or has the upper hand in a situation. However, there are a number of antonyms that express the opposite meaning. One such antonym is "follower," which suggests that someone is taking direction from others rather than leading the way. Another antonym is "subordinate," which implies a position of lower authority or status. Additionally, "powerless" and "helpless" may be considered antonyms of "called the tune," as they suggest a lack of control or influence in a given scenario. Lastly, "team player" may be used as an antonym, as it suggests a willingness to work collaboratively with others rather than asserting one's own agenda.
