Original Wikitext content:
Given a ratio of positive integers p/q, the //kees height// is found by first removing factors of two and all common factors from p/q, producing a ratio a/b of relatively prime odd positive integers. Then kees(p/q) = kees(a/b) = max(a, b). The kees "expressibility" is then the logarithm of the kees height. The set of JI intervals with kees height less than or equal to a odd integer q comprises the [[Odd limit|q odd limit]] The point of kees height is to serve as a metric/height on JI pitch classes corresponding to [[benedetti height]] on pitches. The measure was proposed by [[Kees van Prooijen]]. [[http://www.kees.cc/tuning/perbl.html|Kees tuning pages]]
