Original Wikitext content:
The //apotome//, also known as the Pythagorean chromatic semitone or the Pythagorean major semitone, is the interval 3^7/2^11 = 2187/2048 which is the chromatic semitone in the Pythagorean (3-limit) version of the diatonic scale. Unlike the situation in meantone tunings, it is larger, not smaller, than the corresponding diatonic semitone, which is the Pythagorean minor second of [[256_243|256/243]]. It measures about 113.685¢ and can be generated by stacking seven [[3_2|3/2]] perfect fifths and octave-reducing the resulting interval. See: [[Gallery of Just Intervals]], [[comma]]
