17 equal divisions of 9/2 (abbreviated 17ed9/2) is a nonoctave tuning system that divides the interval of 9/2 into 17 equal parts of about 153 ¢ each. Each step represents a frequency ratio of (9/2)1/17, or the 17th root of 9/2.
Theory
This tuning tempers out 9/8 in the 3-limit, 25/24 and 27/25 in the 5-limit, and 21/20, 35/32, 36/35, and 15/14 in the 7-limit.
