I subscribe to the FE app, and I just have to say what a unique and incredible learning resource it is, and it just continues to get better. Kai, you are an amazing teacher, and the videos are so well produced, thorough, and easy to understand. The new Alegrias videos are the latest example of innovative music education on the site. I would venture to say that there is nothing else like FE out there for any type of music education. Congrats on a brilliantly conceived site!
