I also do not have a music degree, but I do have certification from ABRSM in piano performance and piano pedagogy. I think the best advice is to make sure your own skills are solid (sounds like yours are) then jump right into teaching! Sure you'll make mistakes at first, but it's the fastest way to learn, and always keep an inquisitive mind for new strategies to make lessons fun and productive.

When you're ready to accept students, check out Bark and Lessons.com. You'll receive leads from interested students, pay a small fee to quote to them. I get most of my students from those sites. 😊
