Orwell comma
In musical tuning, the Orwell comma () is a very small musical interval of 13.07 cents and frequency ratio of 1728:1715 or 26·33 : 5·73[1]. It is so named because the temperament eliminating this comma, Orwell temperament, has an optimal generator very close to 19 steps out of 84-equal temperament; this pattern of 19/84 steps is similar to the title of Orwell's novel 1984.
