The Second Vatican Council said that the pipe organ had pride of place among all the instruments used in church for sacred music. The pipe organ is the “king of instruments”.
Here is a super-geeky close examination of the massive pipe organs in the Cathedral Basilica of St. Louis, certainly one of the grandest churches in these USA.
Firstly, the close look at the pipes and mechanisms of these organs is pretty amazing. You can learn a lot about how they work from this video.
However, a super benefit of the video is the view of the church. You see the interior of the magnificent basilica from angles that you couldn’t possibly arrive at on your own. Even if you know the church well, this video will still delight.
