That's a beautiful piece by Rachmaninov.
It's interesting that the Crystal Cathedral has all of those bells, leftover, I presume, from when it was a Protestant cathedral. Probably wouldn't see real bells installed in Catholic cathedrals nowadays. I wonder if there will be any recordings of the Easter bell concerts there.
Right, the bells are in the same tower, and not modified. The tower and bells were designed and built by the same people who built the Crystal Cathedral for Robert Schuller.
That's him in front and the top of his bell tower in the back.
Here is a photo of the adjustment blocks operated by the "keyboard" that controls the 52-bell carillon:
This video shows the operator playing the keyboard, called a clavier. The wooden sticks that she operates by striking them with her hands are called batons. The dynamics of play are controlled by how hard and how fast the batons are struck:
And this video is a tour of the bell tower. Strikers on the outside of the bells are for automatic programs played electronically and the clappers inside the bells are controlled by the keyboard system which is manually operated.
One thing that strikes me (pun?) is the conspicuous RUST you can see on the steel framework. This tower is in Garden Grove, about 5 miles from the Pacific Ocean, and you can smell the sea air. Rust is very prominent problem within coastal areas. When you have steel framework starting to show rust getting through the paint, you have to get right on it or it will become very destructive.
Currently the Cathedral itself is off limits and in process of repairs, but you can walk around under some of the open framework that looks a lot like what you can see here in the bell tower. And it's in similar condition. They're going to have to sand blast or Naval Jelly that rusty paint off the steel like they do on the Golden Gate bridge (where a crew works full time year round stripping and re-painting such that by the time they work their way to the end of the bridge they have to go back to the other end and start over, a cycle that takes over a year). I would estimate that work on the Cathedral is going to be going on for at least a year, perhaps two or more. This rust thing is a big deal.
Here is a 22-minute video on a carillon concert at Christ Cathedral. It seems to me that they're using the carillon for the interim period during renovations when they're "transforming" the place into a "Catholic Cathedral." Supply your own meaning........
