The equal division of 15/8 (ed15/8) is a tuning obtained by dividing the classic major seventh (15/8) in a certain number of equal steps.
Division of 15/8 into equal parts does not necessarily imply directly using this interval as an equivalence. Many, though not all, ed15/8 scales have a perceptually important false octave, with various degrees of accuracy.
The structural importance of 15/8 is hinted by 11\12 being the second most common width for a tetrad in Western harmony, after 10\12.
