{{MOS degrees|Scale Signature=5L 2s|Step Ratio=7/3; 9/4|Genchain Extend=0, 5}} | The flatter end of the hypohard region corresponds to Pythagorean tuning and schismic temperament, with perfect 5ths that are close to 702¢.{{MOS degrees|Scale Signature=5L 2s|Step Ratio=7/3; 9/4|Genchain Extend=0, 5}} | ||
The sharper end of the hypohard region corresponds to "neogothic" or "parapyth" systems, with perfect 5ths that are sharper than 702¢.{{MOS degrees|Scale Signature=5L 2s|Step Ratio=3/1; 5/2; 8/3|Genchain Extend=0, 5}} | |||
