The undevicesimal counterschisma is a 19-limit unnoticeable comma measuring about 0.24 cents. While the undevicesimal schisma (513/512) is the difference between the Pythagorean minor third (32/27) and the otonal minor third (19/16), the undevicesimal counterschisma, in contrast, is the difference between 25 Pythagorean whole tones and the 19th harmonic, or equivalently stated, the difference between the 53-comma and the undevicesimal schisma.
