Pi-EDO, or 3.141...EDO is a nonoctave equal-step tuning in which pi number of steps occur per octave. It does not approximate any simple harmonics well, except for the 3rd harmonic. This lends the tuning to use with custom inharmonic timbres. It has the potential to facilitate music far removed from any conventional harmonic or melodic traditions.
