People often hear the pipe organ more in December than in other months, thanks to the profusion of Christmas-centered church services and concerts. Here to give us a "crash course" on this mighty instrument--its anatomy and its history in various geographical regions--is noted U.S. organ consultant, restorer, and builder John Bishop, owner of John Bishop Organ Consultation. He is also the Executive Director of the Organ Clearing House, whose mission is to "rehome" unused or unwanted organs. Additionally, John writes a monthly column for the organ journal The Diapason.
