Credit for the design goes to Hungarian pianist and composer Emanuel Moor, who came up with it in the 1920s.
"Dual keyboard pianos feature two keyboards, or manuals," the program noted, "which are placed one above the other. The lower keyboard, with 88 keys, resembles that of a typical piano, while the upper keyboard of 76 keys is one octave shorter in the treble but sounds one octave higher than the corresponding key on the lower keyboard. ... Both keyboards can be played simultaneously and a single hand positioned diagonally can play chords that extend over two octaves, thereby expanding the possibilities for playing complex compositions."
This design looks like the easiest to make a kit for, (to cannibalize 2 midi controllers and fit the keyboards as close together as possible); for keyboardists who are looking to expand harmonic reach........

I sumbit that this forum should absolutely NOT consider "backward compatibility with previous notations" to be an advantage in any proposed new notation. That's a dead-weight loss -- a cost that reduces overall consumption from its potential maximum. I submit that this forum's objective should be to GROW THE MARKET -- to dramatically increase the use of music notation by making it simpler and more accessible WITHOUT dumbing it down, even if attaining that goal requires breaking compatibility with notation's previous incarnations (and instruments).
Hmm, that does not seem obvious to me. There are very few precedents of
non-compatibility in notations through history. When the Venetians
developed the slanting lowercase letters that came to be known as
"Italic," it saved space and was quicker to write but it didn't break
compatibility. The two systems lived together and today they still do as
upright and italic.
The only system of notation that I can think of that behaved in history
as you suggest is the replacement of Roman numerals by Arabic. There was
no backward compatibility there and the addition of the zero cinched the
transformation. A new music notation that meets this difficult test has
not come to my attention yet.

So our goal would be to promote and increase the number of people
reading music? I disagree. That's outside of our scope. We are here to
evaluate and deal with systems that improve and might replace TN. If
ease of teaching and potential popularity come in as one consideration,
OK, but that is a prediction. I have heard from every single inventor
that his system makes learning easier. So? Just about any system
invented from scratch would be easier to learn than TN. Surely, we can
agree that this goes without saying.

This has been the weak point in most of the systems I've examined.
Either the inventor didn't want to address the problems of rhythm or he
saw no problems. If we as a group believe that TN's rhythmic notation is
as good as it gets, we should state this. Otherwise, evaluation because
incredibly lopsided as System A using TN's rhythmic component is
compared with System B which was provided by the inventor.
Does anyone here think the pitch component is the only thing that should
be improved?
Does anyone here feel that we might have better cooperation and more
interest if we approached pitch and time separately? (I've always
thought they should be considered together.)
Cheers!
