5L 8s⟨15/7⟩
5L 3s⟨15/7⟩ is a 15/7-equivalent (non-octave) moment of symmetry scale containing 5 large steps and 3 small steps, repeating every interval of 15/7 (1319.4¢). Generators that produce this scale range from 494.8¢ to 527.8¢, or from 791.7¢ to 824.7¢.
Any ed15/7 with an interval between 494.8¢ and 527.8¢ has a 5L 3s scale. 13ed15/7 is the smallest ed15/7 with a (non-degenerate) 5L 3s scale and thus is the most commonly used 5L 3s tuning.
Standing assumptions
The TAMNAMS system is used in this article to name 5L 3s<15/7> intervals and step size ratios and step ratio ranges.
The notation used in this article is G Mixolydian Mediant (LLsLLsLs) = GABCQDEFG, unless specified otherwise. We denote raising and lowering by a chroma (L − s) by # and f "flat (F molle)".
The chain of perfect 4ths becomes: ... Ef Af Qf Ff Bf Df G C E A Q F B D ...
Thus the 13ed15/7 gamut is as follows:
G/F# G#/Af A A#/Bf B/Cf C/B# C#/Qf Q Q#/Df D/Ef E/D# E#/Ff F/Gf G
The 18ed15/7 gamut is notated as follows:
G F#/Af G# A Bf A#/Cf B C B#/Qf C# Q Df Q#/Ef D E D#/Ff E#/Gf F G
The 21ed15/7 gamut:
G G# Af A A# Bf B B#/Cf C C# Qf Q Q# Df D D#/Ef E E# Ff F F#/Gf G

Intervals
The table of Neapolitan-oneirotonic intervals below takes the fourth as the generator. Given the size of the fourth generator g, any oneirotonic interval can easily be found by noting what multiple of g it is, and multiplying the size by the number k of generators it takes to reach the interval.

Hypohard
Hypohard Neapolitan-oneirotonic tunings (with generator between 5\13 and 7\18) have step ratios between 2/1 and 3/1.
Hypohard Neapolitan-oneirotonic can be considered " superpythagorean Neapolitan-oneirotonic". This is because these tunings share the following features with superpythagorean diatonic tunings:
- The large step is near the Pythagorean 9/8 whole tone, somewhere between as in 12edo and as in 17edo.
- The major 3rd (made of two large steps) is a near-Pythagorean to Neogothic major third.
EDIXs that are in the hypohard range include 13ed15/7, 18ed15/7, and 31ed15/7.
The sizes of the generator, large step and small step of Neapolitan-oneirotonic are as follows in various hypohard Neapolitan-oneiro tunings.

Hyposoft
Hyposoft Neapolitan-oneirotonic tunings (with generator between 8\21 and 5\13) have step ratios between 3/2 and 2/1. The 8\21-to-5\13 range of Neapolitan-oneirotonic tunings can be considered "meantone Neapolitan-oneirotonic”. This is because these tunings share the following features with meantone diatonic tunings:
- The large step is between near the meantone and near the Pythagorean 9/8 whole tone, somewhere between as in 19edo and as in 12edo.
- The major 3rd (made of two large steps) is a near-just to near-Pythagorean major third.
The sizes of the generator, large step and small step of Neapolitan-oneirotonic are as follows in various hyposoft Neapolitan-oneiro tunings (13ed15/7 not shown).

Ultrahard
Ultrapythagorean Neapolitan-oneirotonic is a rank-2 temperament in the pseudopaucitonic range. It represents the harmonic entropy minimum of the Neapolitan-oneirotonic spectrum where 7/4 is the major seventh.
In the broad sense, Ultrapyth can be viewed as any tuning that divides a 16/7 into 2 equal parts. 23ed15/7, 28ed15/7 and 33ed15/7 can nominally be viewed as supporting it, but are still very flat and in an ambiguous zone between 18ed15/7 and true Buzzard in terms of harmonies. 38ed15/7 & 43ed15/7 are good compromises between melodic utility and harmonic accuracy, as the small step is still large enough to be obvious to the untrained ear, but 48edIX is where it really comes into its own in terms of harmonies, providing not only excellent 7:8:9 melodies, but also 5/4 and archipelago harmonies, as by shifting one whole tone done a comma, it shifts from archipelago to septimal harmonies.
Beyond that, it's a question of which intervals you want to favor. 53ed15/7 has an essentially perfect 7/4, 58edIX also gives three essentially perfect chains of third-comma meantone, while 63ed15/7 has a double chain of essentially perfect quarter-comma meantone and gives about as low overall error as 83ed15/7 does for the basic 4:6:7 triad. But beyond 83edIX, general accuracy drops off rapidly and you might as well be playing equal pentatonic.
