π/3 occurs in the [[Pitave]] system, which uses a an increase of frequency by a factor of π = 3.14... as an interval of equivalence. Tempering it out means that the pitave is equated to the tritave, 3/1. | π/3 occurs in the [[Pitave]] system, which uses a an increase of frequency by a factor of π = 3.14... as an interval of equivalence.
