genius!
Fascinating.
Astounding. NOBODY could do so much with a simple theme as Bach.
Thanks Cynth! 
Lovely.
Good on ye Cynth, that was a marvellous little thing to see and hear…

awesome!!! Thanks, Cynth!
I’m so glad you enjoyed it. It seemed like a neat way to present it so people could just get an inkling of what was going on.
And that was a TWO part invention.
Now go listen to Art of the Fugue: One theme, developed over and over again into coherent, (at least) 4 voice fugues, with the theme slowed down, sped up, majored, minored, played upside down and backwards …
More genius than my little mind can handel … (pun intended )

My piano teacher was all fired up about Bach. He had an electronic keyboard, and was able to set up a patch that not only sounded like an old clavinet, but also had the Baroque tuning, and would switch this back and forth with modern piano tuning so that I could hear the difference. Much like the pipes, the old sound was richer, but precluded much of the chording used today because the old tuning didn’t stay in tune with itself all the way up, so this dictated the way Bach did some of the things he did.
The animation is excellent. Thx for that, Cynth.

fyffer, my mind couldn’t really handel this one. It just enjoyed it. I can’t imagine what it would feel like to have these sorts of ideas.
djm, that would be really interesting to get to compare the two tunings together. I am actually working my way now into learning about just and equal temperment. First, I have to learn some other things so I can understand what they’re talking about.
Bach himself attributed his “talent” to God. He was merely taking dictation. Everything he did, was for the “Glory of God”.
Just one other reminder to me that “Music comes from - but mostly through …”
Bach lived in an extremist climate and knew which side of the bread would hit the floor first. He was a mathmetician as well as a musician, so he had all sorts of ways of calculating what he was doing and where it would go. The beauty of Cynth’s animation is that it shows you the mechanics of how this stuff went together without you having to be a music major or math genius to understand - you can watch it happen on screen. Its a great idea and a great find. Thanks again, Cynth.

He did and was!
How many of us have noticed
that when we are playing our best
that most of our conscious mind is
standing off to one side,
with it’s mouth agape,
going “whoa! Where did that come from?” 
In college I took both 16th century and 18th century counter-point wherein we studied the “rules” that Bach used to create his inventions and fugues. Lots of stuff going on in these… like the absence (99.5% of the time) of parallel 5ths in his harmonic motion. (a tricky puzzle with 2 voices – a mind scrambler with 4,6,… 8!) Various resolutions and cadences that would facilitate the “requisite” 2 key changes so the theme would develop in 3 keys. Inversions, retrogrades, the works.
Then we had to write our own! 
It was both easy and difficult at the same time. The recycling of existing motifs made for easy arrangement and a wealth of composed material. The tough part came in following all those rules! Very cool exercise. I tend to think that he was just writing what sounded good to him at the time and didn’t worry about such a set of “rules”. It just was what he was about. I still have mine on my computer somewherz.
I really liked that animation. Great 50,000 foot view of how he did what he did. 
Haydn said the same thing. When pressed as to why he almost never wrote in a minor key, he said something to the effect, I write my music for God, and God made me happy and would be displeased if I wrote music that’s against my nature.
As someone who really much prefers minor modes, it amazes me what Haydn and Brahms can get out of major keys. Music that touches the soul without being dark in any way.
