Janko keyboard

The Janko keyboard is a musical keyboard layout for a piano designed by Paul von Janko. Instead of a single row of white and black keys, the keyboard has an array of keys.

  C# D#  F  G  A  B  C# D#  F  G  A  B
 C  D  E  F# G# A#  C  D  E  F# G# A#
  C# D#  F  G  A  B  C# D#  F  G  A  B
 C  D  E  F# G# A#  C  D  E  F# G# A#
  C# D#  F  G  A  B  C# D#  F  G  A  B
 C  D  E  F# G# A#  C  D  E  F# G# A#

For those who are musically literate, you may note that on each row of keys, the interval from one note to the next is exactly one half step. A scale played with all whole steps sounds very different than a regular musical scale.
