1342edt provides a ''very good approximation'' to the [[No-twos subgroup temperaments|no-twos]] [[7-limit]], with the [[5/1|5th harmonic]] tuned 0.55% sharp (approximately 1/181 of a step), and the [[7/1|7th harmonic]] tuned 1.29% flat (approximately 1/110 of a step). Despite the very good tuning of prime harmonics 3, 5 and 7, | 1342edt provides a ''very good approximation'' to the [[No-twos subgroup temperaments|no-twos]] [[7-limit]], with the [[5/1|5th harmonic]] tuned 0.55% sharp (approximately 1/181 of a step), and the [[7/1|7th harmonic]] tuned 1.29% flat (approximately 1/110 of a step). Even with this level of accuracy, it still supports the (relatively) simple temperament [[Izar]], equating six intervals of [[49/45]] to [[5/3]]. Despite the very good tuning of prime harmonics 3, 5 and 7, 1342edt misses the octave, [[2/1]], by 29% (larger than 1/4 of a step), making it incomparable with its related [[edo]]s, [[847edo]] and [[848edo]]. | ||
1342edt is a no-twos [[zeta]] peak and integer peak edt, and can represent prime harmonics from 3 up to 41 with less than 30% of error. It is consistent in the 27-odd-limit (with [[29/19]] being the first interval 1342edt fails to represent consistently) and in the no-29s 39-odd-limit (failing at 41/19). 1342edt can thus be seen as the edt counterpart to [[1578edo]], a zeta edo with similar size, approximation to primes, and consistency limit. | 1342edt is a no-twos [[zeta]] peak and integer peak edt, and can represent prime harmonics from 3 up to 41 with less than 30% of error.
