The equal division of 9/8 (ed9/8) is a tuning obtained by dividing the major whole tone (9/8) into a number of equal steps.

Properties

Division of 9/8 into equal parts does not necessarily imply directly using this interval as an equivalence. Many, though not all, ed9/8 scales have a perceptually important false octave, with various degrees of accuracy.

9/8 is notably the difference between two intervals sometimes considered equivalences: the triple octave (8/1), and the double tritave (9/1).
