294 equal divisions of the octave (abbreviated 294edo or 294ed2), also called 294-tone equal temperament (294tet) or 294 equal temperament (294et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 294 equal parts of about 4.08 ¢ each. Each step represents a frequency ratio of 21/294, or the 294th root of 2.

294edo has a very accurate fifth inherited from 147edo, only 0.086 ¢ sharp, but it has a 5/4 which is 1.441 ¢ sharp and a 7/4 which is 1.479 ¢ flat, so that 7/5 is 2.920 ¢ flat, rendering it inconsistent in the 7-odd-limit.

In the 5-limit 294edo tempers out 393216/390625, the würschmidt comma, and [54 -37 2, the monzisma. The patent val tempers out 10976/10935, the hemimage comma, and 50421/50000, the trimyna comma, and supplies the optimal patent val for trimyna temperament, as well as its 11-limit extension, and also supplies the optimal patent val for the rank-4 temperament tempering out 3773/3750. The 294d val tempers out 16875/16807 and 19683/19600 instead, supporting mirkat, whereas 294c tempers out 126/125 and 1029/1024, supporting valentine.
