Miscellaneous 5-limit temperaments
Below are listed some high-badness 5-limit temperaments (badness > 0.2). Most of these are temperaments which have low accuracy, high-complexity generators, or large number of generators for simple consonances. This is not an exhaustive list. Only expect to find a temperament here if you have not found it in:
- Individual temperament families and clans
- Individual equivalence continua
- Fractional-octave temperaments
- Very low accuracy temperaments
- Very high accuracy temperaments
