The '''19-comma''', otherwise known as the '''Pythagorean kleisma''' ({{monzo|legend=1| -30 19 }}, [[ratio]]: 1162261467/1073741824), is an interval of about 137.1{{cent}}. It is the amount by which nineteen [[3/2|perfect fifth]]s exceed eleven octaves, or (3/2)<sup>19</sup>/2<sup>11</sup>. If used as an interval in its own right, it is the '''Pythagorean inverse double-diminished second'''. Treating it as a comma, [[tempering out]] this comma gives rise to [[graywood]], which is supported by edos 19, [[38edo|38]], [[57edo|57]], and [[76edo|76]] in their [[patent | The '''19-comma''', otherwise known as the '''Pythagorean kleisma''' ({{monzo|legend=1| -30 19 }}, [[ratio]]: 1162261467/1073741824), is an interval of about 137.1{{cent}}.
