Another great thought inspiring post @chbartist, being a learner myself I found it very interesting. Well I say learner but am also a teacher. I believe anyone can teach what they already know and do not need to be an expert in the field to teach. For example I used to teach guitar to children. Although I play other instruments, my guitar skills are very basic, but I know my music theory. So I got a few students and taught them what I knew on guitar and when they were able to match me, I found them another more advanced teacher. The teacher said I had taught them well, given them a good foundation for taking the skill further. I also learned a lot through teaching these kids, it improved my own skills.
Music is a great thing to teach and as you say in your post, some learn using their ear and others need to study written word. I think different learning methods are established young and the schooling people get in their early years sets a pattern for life, so early learning is really important. I love to learn new stuff it’s something I need in my life and I look forward to practice every day. Have a great day 🙏🎻
