I'm going to look at one tomorrow that is in a state of mid-restoration (and has been for some time!)
Wish me luck!
Starting on row one looks a bit awkward at first but starting on row 3 going down to 2 and then 1 is simple. Good game.

Has anyone here tried it?
But on the janko there are Six notes set back into the second row .(See janko Images for a quick check .)
That leaves every note on the keyboard with it`s octave one note physically closer. That is a Massive Bonus if you have small hands .
Surprisingly the janko descriptions do not highlight this important fact.
One oddity in the instructions tells us that only the thumbs should play the lower two rows of notes. But on one video showing a pair of janko players they are using all their fingers on those two lower rows. So it seems that a 2 row janko might be possible . Surely that would give the janko principle a fighting chance of surviving against all odds.
It might be a get out of jail free card for all the players with small hands .
The point about each scale using the same fingering pattern is interesting but not as crucial as a way to save pain and discomfort for so many players .Ladies would appreciate the benefits as well as children .(And me ).
So it is not a full key width difference .
The standard keyboard divides the 7 white keys into 16.4 which makes each key 2.342cms wide.
With a janko division of six lower notes and six upper notes the key width becomes 2.733cms .
The practical business of reaching the octave note is straddling the notes in between. With a division by 6 instead of 7 the notes will become wider but adding up the difference only seems to make the janko reach 0.387 cms shorter.
There are some Yamaha digitals that have a slightly shorter octave already of 15.9cms.That is 0.5cms less than standard.
All that work for just short of one centimetre difference .ie 0.5+0.387= 0.887cms
