|Other musical keyboard designs
This section gives more information about various other keyboard designs related to the Balanced keyboard.
The Music Notation Project - article on Isomorphic
The Music Notation Project is a project which explores alternative music notation systems. Its website
has a page which summarises a number of "Isomorphic" instruments, meaning
instruments whose physical note layout presents musical structure in an
identical or similar appearance of intervals in all transpositions. See
Re-colouring of standard keyboard - The Music Notation Project
The Music Notation Project also discusses a re-coloured variant of the standard keyboard - see
6-6 Colored Traditional (7-5) Keyboard
. According to the web page, it helps the musician to see the interval patterns
between the keys. Note that this layout is NOT the same as the Balanced layout.
The Uniform keyboard - Daskin
Manufacturing / Paul Vandervoort
Paul Vandervoort's Uniform keyboard (produced by his company, Daskin Manufacturing) is based
upon the Janko keyboard design. See the Daskin Manufacturing website at
Symmetrical/Uniform accordions - Hugo Alberto Alzate Londoño
Hugo's interests are in accordions with the "symmetrical" (2-row) and "uniform" (3 or more rows) 6+6
keyboard layouts. Here is Hugo's 2-row symmetrical keyboard accordion which he designed:
Hugo explains: "I am trying to revive the interest of accordionists about the 6+6 system.
There are some videos in YouTube of me playing a 3 rows button accordion and a 2 rows symmetrical
"Also, this 4-row uniform keyboard accordion belongs to Edwin Davison (co-author of the
famous book 'The Golden Age of the Accordion'":

The Symmetrical keyboard
Closely related to the Balanced keyboard is the "symmetrical keyboard", in which Graham Breed modifies
a DX21 keyboard (see http://x31eq.com/instrum.htm)
in a similar manner as described in the Build
one section of this website, but for microtonal music (i.e. with
more than 12 notes per octave) rather than as a generalised replacement
for a standard keyboard.
Bilinear Chromatic keyboard website
Jose Sotorrio discusses the "Bilinear Chromatic" keyboard (a variant of the Balanced keyboard layout),
along with his Bilinear Music Notation system, at
"Intuitive Instruments for Improvisers"
Alternative keyboard designs, with commercially available adaptors to
adapt standard keyboards. The website also has a range of other
interesting ideas. See http://improvise.free.fr/
