a Janko xylophone, "Tri-Chromatic Keyboard"

[William Croft]

Roy Pertchik's invention with a unique tri-coloring scheme.

Roy also has a thread on this on the Dorkbot Boston group:
http://groups.google.com/group/dorkbotboston/browse_thread/thread/838ac244f70856d9

The coloring scheme is unique and I think could make finding intervals
easier on a large layout such as the xylophone.

Maybe Roy can also tell us his source of chromatic xylophones and who
applies the coloring scheme (Roy or the manufacturer).

Roy, feel free to join the diykeyboard group (do it yourself keyboard
fans).

A few additions, here is Roy's website:

And the patent on the coloring / layout he is using:

His instrument by the way is a vibraphone, not just a xylophone.

I did a google search on the term "chromatic xylophone" and this is
just interpreted as the standard piano key style layout. I guess a
diatonic xylophone would be without the accidental keys (probably only
found in playgrounds!)

But that begs the question, what is a janko xylophone called?
Searching on that of course turns up nothing. If anyone knows of any
manufacturers of these, "chime" in.

The manufacturer of Roy's custom layout vibraphone is Nico vanderPlas:

Well... we can dream I guess.

Hi Roy;

 

What are the note names

Hi Roy;

 

what are the note names? - since it doesn't look like a 6-6 - (w/black and white keys)

 

can you explain row 1 (red black silver, f,g,a ?) row 2 (red black silver, c,d,e?) etc.

Paul, see the patent link.  It's a normal 6-6 layout with the novel addition of his coloring scheme which allows some orientation landmarks which are scale agnostic.  Vs. the original Janko which colored conventional accidentals.  And the Chromatone (NO landmarks), which people end up putting little magic-marker dots on the keycaps to find their way around.  :-)

Roy has asked Andrew for diykeyboard group membership, which I think will be approved momentarily.

Hi Folks, Roy here :-)

Thanks for all of the interest. I am studying a symmetrical
understanding of music. It's a formulation of harmony using the three
diminished arpeggios to organize everything else. It's unbelievably
powerful. It's also really hard to learn on the conventional
keyboard, but becomes very clear on my keyboard. The color scheme I
use emphasizes families of dominants, and the scales I use include for
example in the Major, a dominant on the 5th and a dominant on the
3rd... one for the Major, and one for the relative minor... it's very
powerful. I need to make more music video demos showing this, because
transposition is just one thing, but the understanding of theory that
comes from my system is really strong.

The names of the 12 notes going up chromatically from F, are Bae, Ree,
Wie, Boe, Ray, Wee, Bie, Roe, Way, Bee, Rie, Woe, and back to Bae.
These are pronounced so that they rhyme with the vowel names A, E, I,
and O (there is no U :-)

The concept is the first letter rotates through 3: B, R, and W for
Black, Red, and White, my colors. The vowel sound rotates through 4
choices, ae, ee, ie, and oe. Combining the 3 initial letters with the
4 vowel sounds yields 12 permutations, one for each note. The neat
thing is, there is complete symmetry of the mnemonics in every key.
For example, the vowel of the 1st and Maj3rd is always the same, the
first letter of the 1st and 3rd always moves through the rotation from
dark to light (black to red, red to white, white to black...) and so
forth for any property you observe,.. symmetry is maintained in every
key.

For those interested, I can forward a paper I have written with in
depth descriptions of the system. Many of you will fine a lot of the
into info completely familiar, but the description of my designs may
be of interest.

Does this group site have a place to upload documents?

Cheers

Hi Roy-

We keep GPL'd design documentation, code, etc. that is a part of the
diykeyboard project in a subversion repository. The wiki is less
strict; you can post pretty much anything, although anyone is welcome
to change it after you. Correct factual information is very unlikely
to be messed with, though. We're still on Wikidot for the time being
since I haven't yet found a wiki host I like enough to spend the time
it would take to transition the wiki. Send me your wikidot account
and I can add you.

Cheers,
Drew

Hi Drew,

Thanks for the info. Except, I'm not sure what GPL'd is, and I don't have a
Wikidot account (don't really know what that is... I looked there now.. is
there a free option just to belong?)

Sorry for my ignorance.

Roy

is a way to give others permission to use, modify, redistribute,

release it under the GPL without fear of being sued.

Ok, thanks

Hi Drew,

I've opened a Wikidot account with the cryptic name Roy Pertchik. Please
add me to DIYKeyboard.

Thanks
