'''Richie's HEJI extensions''' are a set of 9 pairs of accidentals, designed by [[richie]], that extend [[Helmholtz–Ellis notation]]'s accidentals from the [[47-limit]] to the [[89-limit]]. These allow the [[Musical notation|notation]] of [[just intonation]] intervals with much higher prime factors, which are encountered relatively often with some approaches to JI such as [[primodality]]. | '''Richie's HEJI extensions''' are a set of 9 pairs of accidentals, designed by [[richie]], that extend [[Helmholtz–Ellis notation]]'s accidentals from the [[47-limit]] to the [[89-limit]].
