Teach poetry as long as you are not afraid of notation.

Well, it shows that you have a great talent for music. My father is like this. He can't read music, but as long as he can sing, he can play. Then his musical talent was passed on to me, so I learned music. In our music major, there is a course called solfeggio, that is, to be able to hear any melody, you can write it with music scores. Of course, due to the short study time, I haven't been able to do it yet. But listening is ok. If you want to learn music score, learn simple notation. There is no need to learn the staff. You can go to the bookstore to buy a book called Music Theory. It should be enough for you to look at some basics, just look at the score, and add some musical terms, such as some decorative sounds, and composing music is a process of practice. You can't master it in a day or two.
