Get ready for a weekend, hopefully on this side of the Jordan River, with Johnny Cash's Wayfaring Stranger.

Plagues and Pestilence

Deadly pandemics are a feature of living that the West, largely through vastly improved sanitation, have reduced over the last Century. Still, as this list of Cholera outbreaks shows, outbreaks still bloom from time to time.

Being such a feared aspect of life, plagues, pestilence and death by disease were naturally a subject of art. Here, and below the fold, are a few examples of such art.

The Von Jankó Keyboard

While on vacation I stopped at the Stephen Foster Folk Culture Center in  White Springs, Florida. One of the pianos they had on display was the one pictured above, featuring a Von Jankó keyboard.

It had never crossed my mind, but of course piano keyboard layouts are arbitrary and -- like mousetraps -- innovators are bound to try to improve upon them. in 1882 Paul von Jankó devised a keyboard with a 6-6 layout. As described at the Music Notation Wiki:
Because it has an isomorphic layout, each chord, scale, and interval has a consistent shape and can be played with the same fingering, regardless of its pitch or what the current key is. If you know a piece of music in one key you can transpose it simply by starting at a different pitch because the fingering is the same in every key.

This provides much more consistency than the traditional keyboard layout where each chord, scale, and interval has multiple shapes and requires learning multiple fingering patterns. On the Jankó layout there are twelve times fewer chord shapes and scale patterns to learn. This greater consistency also improves awareness of interval patterns and harmony, and makes it easier to improvise and play by ear.

You can go to the following link to fiddle around with Jankó style isomorphic keyboard.
Because few pianists were willing to relearn their repertoires for the new keyboard few Jankó style pianos were ever built. Lack of demand eventually led to their demise.

A Bionic Rube Goldberg Machine

It strikes me this video is actually a facsimile of a Rube Goldberg Machine. The real machines are overly complicated pieces of nonsense to do mundane tasks, while this is an overly complicated sequence to do nothing but advertise Red Bull. Still, it is clever in shirt-tail riding sort of a way.

I've been sick, so my posting has been non-existent.  I hope to bounce back soon. The above painting by Wassilij Maximowitsch Maximow captures my situation perfectly -- me sick in my rustic cabin, laying under pictures of saints, and with Mrs. Sinistral praying for me.

OK, maybe one or two details are off, but let's not quibble over the small stuff.
