The Dodeka Keyboard design is an isomorphic keyboard invented and designed by Jacques-Daniel Rochat. It is similar to a piano keyboard but with only a single row of keys containing each chromatic note.[1][2] The keys corresponding to C, E and A flat are highlighted to provide visual landmarks. The creators aimed to create a rational and chromatic approach to music and performance.[3] As an isomorphic keyboard, any musical sequence or interval has the same shape in each of the 12 keys.

Music notation

The Dodeka design was developed together with the Dodeka Music Notation.[4][5][6] It consists of a four-line chromatic staff, and represents rhythms only using the visual length of a bar on the staff, reminiscent of the appearance of "piano roll" in digital audio workstations.
