This section describes step ratio ranges for 5L 2s and what rank-2 temperaments they correspond to. Although the two may have closely correspond with one another, the purpose of step ratios is to describe 5L 2s without necessarily using [[regular temperament theory]]. | |||

The range of | The range of hard step ratios can be divided into a minihard range (2:1 to 5:2), quasihard range (5:2 to 3:1), parahard range (3:1 to 4:1), and ultrahard range (4:1 to 1:0). Specifically, the minihard range corresponds to Pythagorean tuning and schismatic temperament, quasihard to "neogothic" or "parapyth" systems, and parahard and ultrahard to "archy" systems. | ||
