383edo is the equal division of the octave into 383 parts of 3.13316 cents each.

Theory

383edo is distinctly consistent through the 15-odd-limit with a flat tendency. It tempers out 32805/32768 (schisma) in the 5-limit; 2401/2400 in the 7-limit; 6250/6237, 4000/3993 and 3025/3024 in the 11-limit; and 625/624, 1575/1573 and 2080/2079 in the 13-limit and it supports sesquiquartififths.

383edo is the 76th prime edo.
