Non-over-1 temperament

A non-over-2 temperament, or non-/2 temperament, is a regular temperament that tempers a subgroup corresponding to a harmonic series chord r:n₁:...:n_k where r ≠ 2, but not a chord of the form 2:m₁:...:m_k. Non-over-2 temperaments give regular-temperament interpretations to edos that approximate over-2 chords such as 4:5:6:7:11 poorly, such as 14edo, 18edo, 23edo and 29edo.
