400{{cent}} is the most commonly used approximation to [[5/4]], mainly due to its use in [[12edo]]. This interval is also expressed as [[3edo|1\3]], and its square root on the logarithmic scale, ≈692.82{{cent}} (hereinafter expressed as 1\√3 for convenience), functions as an approximation of [[3/2]].

(The comma between these two intervals is called as [[Caffeinterval]].) Furthermore, the interval divided into √3 equal parts with 1\√3 as the center{{clarify}} is ≈985.641¢, which works as an approximation of [[7/4]] or [[9/5]], and the [[tetrad]] that combines these is 4:5:6:7, the so-called It will be the C7. Applying this property, the scale that is created as a result of recursively dividing those intervals furthermore twice is Redbull. | ||
Most of the notes on this scale are irrational numbers in both cent and frequency units, so Redbull cannot be reproduced with an [[edo]]. Also, since there is no interval that can be called a generator, it is also impossible to approximate Redbull with a [[mos scale]]. Also, since there is no interval that can be called a generator, and it varies even by one step{{clarify}}, there are many intervals within Redbull that approximate [[just intonation]], just like [[afdo]]s. | Most of the notes on this scale are irrational numbers in both cent and frequency units, so Redbull cannot be reproduced with an [[edo]].
