'''100/81''', the '''classical grave major third''' or '''diptolemaic major third''', is a [[81/80|syntonic comma (81/80)]] flat of [[5/4]]. It can be obtained by stacking two [[10/9|small whole tones (10/9)]].


'''100/81''', the (classical) '''grave major third''', is a syntonic comma [[81/80]] flat of [[5/4]] and [[325/324]] sharp of [[16/13]], as well as being just [[1701/1700]] flat of the interval [[21/17]]. It is obtained by stacking two [[10/9]] small whole tones.
In the [[13-limit]], it is a [[325/324|marveltwin comma (325/324)]] sharp of [[16/13]], and in the [[17-limit]], merely a [[1701/1700|palingenetic comma (1701/1700)]] flat of the interval [[21/17]]
