473 equal divisions of the octave (abbreviated 473edo or 473ed2), also called 473-tone equal temperament (473tet) or 473 equal temperament (473et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 473 equal parts of about 2.54 ¢ each. Each step represents a frequency ratio of 21/473, or the 473rd root of 2.
473edo is inconsistent to the 5-odd-limit with large errors on both harmonics 3 and 5. The equal temperament is most notable for tempering out the kleisma, 15625/15552, in the 5-limit and 5120/5103 in the 7-limit, providing the optimal patent val for the 7-limit countercata temperament.
