The Jankó keyboard, an 1882 replacement for the traditional piano layout

The Jankó keyboard is a musical keyboard layout for a piano designed by Paul von Jankó in 1882. It was designed to overcome two limitations on the traditional piano keyboard: the large-scale geometry of the keys (stretching beyond a ninth, or even an octave, can be difficult or impossible for pianists with small hands), and the fact that each scale has to be fingered differently. Instead of a single row, the Jankó keyboard has an array of keys consisting of two interlocking manuals with three touch-points for each key lever. Each vertical column of keys is a semitone away from its neighboring columns, and on each horizontal row of keys the interval from one note to the next is a whole step.

This key layout results in each chord and scale having the same shape on the keyboard with the same fingerings regardless of key, so there is no change in geometry when transposing music.

See this Jankó keyboard design in action on a variety of keyboards, including a Paul Vandervoort-built Jankó played by Willem Feltkamp, above. The music: Lagrima by Francisco Tárrega.
