I stumbled upon this live recording of a PROCESSIONAL I played on the pipe organ in 2002. It’s an excerpt from a much longer composition by Sebastian Bach. In those days, there weren’t sophisticated recording devices allowing one “fix” wrong notes. (Perhaps they existed, but we didn’t have machines like that.) So it was necessary to play the entire piece from beginning to end. If you’re a church organist, feel free to download the PDF score. I suppose it’s only a matter of time until some joker uses “artificial intelligence” to play music at church … but there’s something so satisfying about playing an organ in real life.
