Español Tuning theory can become heavily mathematical, and here are links to some of the pages which wade into deeper waters.
It is recommended to read the pages listed on general theory first before exploring this page, as they lay the groundwork.
Intervals
Interval metrics
Chords
Musical information theory
- Categorical Entropy, Mutual Information, and Channel Capacity
- Harmonic entropy
- The Riemann zeta function and tuning
- Maximal dissonance tuning
Interval classification
- Delta-N ratio
- Non radical intervals with musical significance
- abc, high quality commas, and epimericity
- Don Page comma
Lists of factorizations
- List of 3-limit factorizations
- List of 5-limit factorizations
- List of 7-limit factorizations
- List of 11-limit factorizations
- List of 13-limit factorizations
