Playing Peter Reinerts Janko piano.jpg

Hi, my name is Rico.
I explore, build and play
Janko pianos.

The Janko piano design was invented by Paul von Jankó in the late

19th century.

 

It has the very convenient property that it is isomorphic.

Thus, scale fingerings and chord shapes are the same in all keys.

You can't really buy Janko pianos anywhere else which led me to developing, building, and experimenting with Janko pianos myself.

 

My wish is that everyone interested in this piano layout has the possibility to get one and learn how to play it.
