The experience is personal. There is a big difference between knowing and doing. Many people do not know this differently. Would you like to specialize in a subject? Then I suggest you pay attention to this difference. You may be asking why? Let’s explain this topic with an example. If you want to play an instrument, you can get a lot of theoretical information. You can even compose the symphony. However, if you are playing an instrument, you can detect problems. For example, why are you asking why you couldn’t catch a tune? Are you asking why you cannot create a composition? If you are interested and continue to learn, these questions will lead you to many answers. It is important to hear the music, but playing a musical instrument is even more important.
