Why Just Intonation?

A summary~

Why Just Intonation?

1. Just Intonation is based on the harmonics relations one finds in nature and is a natural product of the sounds we hear.

2. Just Intonation represents the most consonant intervals. It likewise can create great dissonances thereby extending the range of tension between the two.

3. Just Intonation is tunable by ear due to its acoustical qualities that are unambiguous in nature. This in turn gives one a palette of limitless emotional depth and flexibility.

4. Just Intonation is a modular system. . It is infinitely expandable in terms of intervals at one disposal. Just intonation scales are also ‘open’ scales. While they can form self-contained consistent structures, they are always capable of being augmented in many different ways. This though does not require having to change or discard the pitches one already has, the array of building blocks are the same.

5. Just Intonation allows perceivable structural possibilities that cannot be realized effectively any other way. While ambiguousness has it place in all the arts , It should be by choice.

6. One can have many different intonation systems and scales yet still have common tones, intervals and even scales common between them that can act as bridges. These easily can exist side by side. In a free world of any pitch at any time one can move from one system to another freely by common tone scales or chords.

7. As Just Intonation produces scales with unequal size intervals, this gives one the possibility of more different size intervals with fewer notes.
For example there are Just Intonation pentatonics that give one more different intervals than 12-tone equal temperament. As another example one particular 7 limit 12 tone scale harmonic known as Centaur will give one 50 different intervals within the octave.

8. Just Intonation allows for the possibility of each key or area of the tuning having its own unique flavor and quality.
