The most important lesson that I have learned after thoroughly experimenting with the mathematics of equal temperament, unequal temperament and just intonation is that perfection cannot be achieved in the theoretical world of tuning.
Something must always be compromised in order to gain something else. This statement is true for all tuning systems:
- Equal temperament. Symmetry is completely gained and key colour is completely lost.
- Meantone temperament. Purer thirds are gained and a wolf fifth emerges.
- Unequal temperament. Some intervals are more pure and some intervals are less pure.
- Just intonation. Harmony is maximised and commas emerge.
- Adaptive just intonation. It makes just intonation practical and it cannot be used for instruments of fixed pitch.
However, the ideal theoretical compromise can be achieved.
It can be achieved by striving for two things. Those two things are simplicity and practicality.
Equal temperament is the simplest and most practical tuning system due to its complete symmetry and consistency.
It solves the commas of just intonation, tames the wolf fifth of meantone temperament, is much more mathematically simple than unequal temperament and can be used for instruments of fixed and variable pitch, unlike adaptive just intonation.
Therefore, equal temperament is the ideal theoretical compromise.
This is the conclusion that I have reached after thoroughly experimenting with the mathematics of equal temperament, unequal temperament and just intonation.
