Hello! Writing to ask for digestible pieces to learn as a person who has played keyboards for many years and received classical training but never played the organ. I'll be having the opportunity to practice at a local church very occasionally as a favor from a friend. Next week I'll hopefully be able to spend an entire morning there, and I was thinking of what I should try doing. Organs look so confusing, like the inside of a computer xD and no-one plays it there so I don't have anyone to answer my questions. Any advice is appreciated.
