The landscape comma is the 7-limit unnoticeable comma with a ratio of 250047/250000 and a size of 0.33 cents. It is the amount by which three 63/50 intervals exceed an Octave, and is also the amount by which a stack of three septimal kleismas falls short of the Pythagorean comma. Tempering 63/50 interval into one degree of 3edo (exact 400 cents) is highly characteristic of landscape tempering- any tuning system (41edo, for example) in which the number of divisions of the octave is not a multiple of 3 cannot temper out the landscape comma.
