11 steps of this temperament is an extremely close approximation of 9²:13², having only 0.5% relative error. 6 steps is exactly 9²:11² (since 3 steps is 9:11), so 9²:11²:13² (81:121:169) is well approximated, which represents the approximate 2:3:4 created by overtones of chimes.<ref>[https://en.wikipedia.org/wiki/Strike_tone#Tuning_a_bell Wikipedia | ''Strike tone'']</ref> | |||
9²:11²:13²:17² is also very well approximated, but 9²:15² has around 25% relative error. | 9²:11²:13²:17² is also very well approximated, but 9²:15² has around 25% relative error. | ||
