Organ Lessons

---


Grandma and the boys at the organ; M is playing the foot pedals and K is playing the Great manual.

Today, we all went to Jackson to meet with a master organ player (my mom) to learn how organs work, and what it takes to play one.

We first got to look at some old and new organ pipes, some made of wood and some of metal. Do you know the difference between a string pipe, principal pipe, and reed pipe? We do now! (Here's an article about organ pipes and how they work.)

The top keyboard is the Swell manual, and the bottom keyboard is the Great manual. There are stops for each, and there are options to allow the Swell settings to be applied to the Great manual.


K plays a Christmas-y tune on the Great manual.

Each of us got to play a song or two on the organ as mom showed us different ways of setting the stops, using the pedals, and our favorite, the Sforzando setting. Sforzando is another of way of saying "really loud".

We also got to go behind the scenes to see the air compressor and pipes. The organ at the church is tuned three times a year, and was renovated about 20 years ago during a larger renovation of the church and sanctuary.


M is playing sforzando in this picture - the little red light just to the right and above the Swell manual indicates "Sforzando". I suggest using this setting when you're playing your favorite song.



M and K are pretty impressed with the whole setup.

Thanks for the organ lessons, mom! We have a new appreciation for what a complex instrument it really is.

Christmas Wrap-Up

Reflective City by Matthias Adolfsson

It's time for a Christmas wrap-up.

We had two very Merry Christmas get-togethers this year - one at our house with my side of the family, and one at J's parents' house for hers. We're lucky (as always) to have our families and always enjoy seeing as many of them as possible over the holidays.

On New Year's Eve, the Spartan football team will play Alabama for a chance to be in the national championship game. Go Spartans!

All of us Ann Arborites, plus Laurie, went to see Star Wars: The Force Awakens. It was well done, I could follow along even though I can only remember the basics of the original movies (and that's all you need to know, by the way: the basics).

If your metal lathe and mill is collecting dust on your workbench, here's a gyroscope project for you.

The Malaise Weeks

---
It's the middle weeks between Thanksgiving and Christmas, also known as The Malaise Weeks. (Not really, I just made that up.)

Let's un-malaise it with some fun stuff.


I love this - 75 hours of illustration in a 2-minute video.

Nancy sent me a link to this puzzle, saying she didn't want to solve it herself. I almost finished it, but have some errors, and I think I've spent enough time on it for a while. I was hoping it would work with the errors in it, but it doesn't. I am being a little cryptic in my description of it in case you want to try to solve it yourself. If you finish it, and don't know what to do with the results, let me know. Dad, get started...

Some of you know I'm a fan of Edward Tufte for his information-related graphics. Here's more of the same.

A rubber-band powered locomotive, made from laser-cut pieces. Cool!

It's always been a dream of mine to play the subcontrabass flute. It may be too late for me to put one on this year's Christmas List.

Christmas Vacation for the kids (and me!) start soon. Nothing busts the malaise more than a little time off work and school...
