The 8<sup>th</sup> Octave Overtone Tuning, sometimes known as 128 Tuning, is a tuning developed by [[Johnny Reinhard|Johnny Reinhard]].
{{Infobox harmonics|128}}


It consists of harmonics of the [[OverToneSeries|harmonic series]], numbers 128 (2<sup>8</sup>, hence 8<sup>th</sup> octave) through 255.

Scales can be selected as subsets of these 128 pitches, or the entire set can be used.
The tuning was developed by [[Johnny Reinhard]]. It differs from the scale only in that it has a fixed root and cannot be rotated. It consists of harmonics 128 (2<sup>7</sup>, hence 8<sup>th</sup> octave) through 255. Scales can be selected as subsets of these 128 pitches, or the entire set can be used.


A key benefit of using pitches exclusively from the same harmonic series is that they share a fundamental. By using the 8<sup>th</sup> octave of a harmonic series, said fundamental will almost certainly be [https://www.merriam-webster.com/dictionary/infrasonic infrasonic], but it will still have a [[wikipedia:Psychoacoustics|psychoacoustic]] presence.

An illustratively surprising result of this higher harmonic tuning is that, since a just 4/3 does not have a power of 2 in the denominator and thus does not exist in the (octave-reduced) harmonic series, it will not be used in this tuning. Instead, when the inverse of the 3/2 ratio is needed, one may use 43/32 (511.517706¢) or 171/128 (501.423018¢).

== Reading ==
Due to having only one prime factor (2), yet also being a higher octave of a prime mode (mode 2), it is a very strong tuning for [[primodality]], providing a large gamut of intervals without compromising their clear prime identity.
