That was great, Bach would have approved. What organ are you playing. The registration was perfect for the piece.

What is "registration"?

Registration is the term given to the combination of pipe voices (e.g. strings, trumpet, tuba, etc.) that is being used for a particular piece of music. The voices are selected with a mechanism called a stop. On the organ in the video, it is the row of tabs across the top right above the keyboard.
