Ploidacot/Tetracot/Generator tunings: Difference between revisions

For most of its generator range, [[7L 6s]], [[7L 13s]], and [[13L 7s]] are the chromatic scales of the family of temperaments which divide the perfect fifth into four equal parts, thus representing 81:80 (the syntonic comma) by +7 or −13 generators. In fact, this comma, which may be inflated to as much as 60¢, appears as the difference between the generator and the disjunct tone and as the small step when the generator is flatter than 3/20edo.{{todo|cleanup}}
