A '''patent interval''' of a (mostly just) interval is the number of EDO steps of the "best" mapping of an interval in a respective EDO. It's calculated by rounding the product of [[Wikipedia: binary logarithm| binary logarithm]] (''log2'') of the interval ratio (''r'') and the EDO number (''nEdo''). | A '''patent interval''' of a (mostly just) interval is the number of EDO steps of the "best" mapping of an interval in a respective EDO.
