" Even J.S. Bach had to put up with these limitations and the harmonic impurity they engender. I'm sure that he would be delighted to use electronic musical instruments if he were alive today." - Wendy Carlos

Music evolves.

It is the goal of Justonic Tuning Inc. to restore the lost harmonic foundations of music that were sacrificed because of the limits of an earlier technology.



Music has at last been unchained from the mechanical, seventeenth century, equal tempered scale.




Musicians will soon discover that with the Justonic system the tonal palette has been expanded to allow virtually infinite combination of scale and tonal flexibility.



Music evolves, and returns to where it all started. This is only the beginning.

The Story of Harmony



Welcome to Justonic Tuning Inc.

The "insurmountable" tuning problem called the "Pythagorean comma" has been solved! The Justonic Tuning Cube can retune an electronic music synthesizer in real time, allowing pure harmony to be maintained in every chord.

Using the Justonic Pitch Palette, any musician playing a MIDI keyboard or MIDI guitar connected to a computer and music synthesizer can now perform in real time just intonation by playing the root note on a MIDI tuning channel. The Pitch Palette MIDI tuning software does the rest sending a MIDI system exclusive tuning message to the synthesizer. The data for the message for every roor within every key comes from the Justonic Tuning Cube. The cube is created from a 12 note scale of 12 ratios. The alternative tuning possibilities within an octave are endless.
