34 zeta peak index (abbreviated 34zpi), is the equal-step tuning system obtained from the 34th peak of the Riemann zeta function.
Tuning | Strength | Closest EDO | Integer limit | ||||||
---|---|---|---|---|---|---|---|---|---|
ZPI | Steps per octave | Step size (cents) | Height | Integral | Gap | EDO | Octave (cents) | Consistent | Distinct |

Intervals
JI ratios are comprised of 16-integer-limit ratios, and are stylized as follows to indicate their accuracy:
