=== Equivalence === | === Equivalence === | ||
Few would argue that 9/4 itself could be heard as an equivalence. Some might argue that some degree of 3/2 equivalence may be possible in a scale which has no 2/1, 3/1, or 4/1, though this is quite controversial. If that is the case, then perhaps in a similar scale that also has no 3/2, 9/4 may have some form of faint equivalence as it might sound like two periods of 3/2. | Few would argue that 9/4 itself could be heard as an equivalence.

=== 5ed9/4 === | |||
Completely misses [[2/1]] and [[3/1]], but aproximates [[5/1]] maybe passably, and [[7/1]] extremely well. | |||
This makes it still posess some useful consonances, but with neither an octave nor tritave to pull the listener's ear — making it a prime candidate for perceptual 9/4-equivalence, if such a thing is even possible. | |||
Every other step of [[5edf]]. | |||

=== 9ed9/4 === | |||
Every other step of [[9edf]] (almost exactly every other step of [[Carlos Alpha]]). | |||
{{Harmonics in equal|9|9|4|intervals=prime}} | |||

=== 11ed9/4 === | |||
Every other step of [[11edf]] (almost exactly every other step of [[Carlos Beta]]). | |||

=== 29ed9/4 === | |||
A compromise between [[39edt]] (triple Bohlen-Pierce) and [[25edo]], combining the benefits and drawbacks of both systems while being audibly different from either. | |||
Every other step of [[29edf]]. | |||
{{Harmonics in equal|29|9|4|intervals=prime}} | |||

A compromise between [[58edt]] and [[37edo]], combining the benefits and drawbacks of both systems while being audibly different from either. | |||
Every other step of [[43edf]]. | |||
{{Harmonics in equal|43|9|4|intervals=prime}} | |||
=== 45ed9/4 === | |||
Very similar to [[61edt]] but improves on its approximations of [[JI]]. | |||

A compromise between [[64edt]] and [[40edo]], combining the benefits and drawbacks of both systems while being audibly different from either. | |||
