The idiom "Johnny-one-note" is a colloquial expression used in American English to describe someone who consistently repeats the same thoughts, ideas, or actions without any variation or flexibility. It can be compared to the idiom "jack of all trades, master of none," which refers to someone who has a superficial knowledge or skill in many areas, but lacks expertise in any specific one. While a "jack of all trades" may possess a range of abilities, they are often considered to be lacking in depth or mastery. In contrast, a "Johnny-one-note" is someone who is hyper-focused on a single idea or topic, disregarding any other perspectives or possibilities. They are characterized by their one-dimensional and monotonous approach.

In the idiom "all one's taste is in one's mouth," the focus is on the individual's limited preferences or interests. Someone who embodies this idiom is only interested in a single thing, and their enjoyment or satisfaction is derived solely from that particular area. This idiom highlights the narrowness of their focus, similar to a "Johnny-one-note" who fixates on one idea or topic to the exclusion of others. Both idioms emphasize the absence of variety and the limitations of their perspectives.

The repetitive singing made the performer one-dimensional.

The idiom "jill of all trades" is the female counterpart to the aforementioned "jack of all trades." Just like a "jack of all trades," a "Jill of all trades" is someone who possesses a variety of skills or knowledge in different areas. However, similar to a "Johnny-one-note," a "Jill of all trades" may also lack specialization or expertise in any one field. They are versatile and able to adapt to different situations, but their knowledge or proficiency may not go beyond a certain level. Despite the similarities, it is important to note that a "Jill of all trades" has a broader scope than a "Johnny-one-note" and is not limited to a single idea or topic.

The idiom "harp on one string" is another expression that can be related to the concept of being a "Johnny-one-note." It refers to someone who continuously focuses on a single point or issue, repeatedly discussing or emphasizing it to the exclusion of other matters. This idiom emphasizes the repetitive and relentless nature of their approach, similar to the monotonous behavior associated with a "Johnny-one-note." However, it is worth noting that "harp on one string" does not necessarily imply a lack of flexibility or adaptability, but rather an excessive fixation on a particular topic.

Overall, the idiom "Johnny-one-note" can be compared to various related expressions such as "jack of all trades, master of none," "all one's taste is in one's mouth," "Jill of all trades," and "harp on one string." These idioms highlight different aspects of repetitive behavior, narrow focus, or limited understanding. While a "jack of all trades" lacks expertise and depth, a "Jill of all trades" has a broader range of skills but may still lack specialization. Similarly, someone whose "taste is in their mouth" and a person who "harp on one string" both demonstrate a fixation on a single area, disregarding the need for variety or different perspectives. In contrast, a "Johnny-one-note" is someone who continuously repeats the same thoughts or actions, displaying a one-dimensional and monotonous approach. By understanding these related idioms, we can better appreciate the nuances and implications of being a "Johnny-one-note" and the importance of embracing diversity, flexibility, and adaptability in our thoughts and actions.
