A perfect Ringer ''n'' scale is one that by some val can map the first ''n'' odd harmonics to distinct numbers of steps up to [[octave equivalence]]. It is | A perfect Ringer ''n'' scale is one that by some val can map the first ''n'' odd harmonics to distinct numbers of steps up to [[octave equivalence]].

Notice how all of these do not skip any harmonics while representing the harmonic series ''completely'' up to some [[odd-limit]]. | Notice how all of these do not skip any harmonics while representing the harmonic series ''completely'' up to some [[odd-limit]]. | ||
Also note that there is a "Perfect Pseudoringer 9" if we allow a pair of harmonics to be swapped/out of order in order to preserve the constant structure property. | |||
