^{9}(semiconvergent)

**512 equal divisions of the octave** (abbreviated **512edo** or **512ed2**), also called **512-tone equal temperament** (**512tet**) or **512 equal temperament** (**512et**) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 512 equal parts of about 2.344 ¢ each. Each step represents a frequency ratio of 2^{1/512}, or the 512th root of 2.

With only a consistency limit of 5, this 9th-power-of-two edo does not have a whole lot to offer in terms of lower harmonics. Harmonic 3 is about halfway between its steps, making it suitable for a 2.9.5.21.17.19.23 subgroup interpretation, with optional addition of either 11 or 13.
