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.
