Hi, I would like to open the organ improvisation topic, because no one is talking actually about it. It is important to us, organist to earn the ability to improvise. It’s part of our jobs, and it is not easy to learn, it takes a lot of affort to learn it. As a beginner organist myself I would like to hear about your stories, how you began with it, maybe some fun anecdotes even. And what would you recommend, what schools of improvisation did you learn?
