Attention! Piano keyboards have a manufacturing defect.

- discovered by Gregory Shir!

It seems there is a manufacturing defect built into current piano keyboards.
Believe it or not, the intervals on the standard piano are NOT equal!

I highly recommend Herr Gregory Shir's redesigned keyboard because it equalizes the upper width of the white keys.
--- Ms. Alvina Louie playing and commenting on Mozart piano

Because intervallic distances are more predictable, the C# (Db) and D# (Eb) keys are technically more accessible in all hand positions, irrespective of individual hand anatomy or finger patterns.
--- Ralph Alberstrom

It seems there is a manufacturing defect built into piano keyboards.
Believe it or not, the intervals on the standard piano are NOT equal!
Lay a finger between C# and D# notes, now lay your finger between F# and G# - you can feel the difference between the two pairs.
Between some white and black keys there are different distances. It's only about 3mm, but that is a big difference when you are trying to sightread without watching your hands.

When the intervals ARE equal, difficult classical pieces are easier to play. Look at our friend playing with her
EYES BLINDFOLDED:

Fur Elise-L.Beethoven 1st
by Hranush Martirosyan - With closed eyes

Hranush Martirosyan first playing on prototype of new Mozart Piano with closed eyes:
"I`m not saying 'su ym ssik' like Mozart - only 'close my eyes!'
"I agree! The new piano made by G. Shir with changes in the layout of the keys, makes piano playing easier."
