This article uses the convention JKLMNOPQR = LSLSLSLSL and pitch standard J = C4 = 261.6255653 Hz. The accidentals & and @ are used for raising and lowering by the chroma = L − S, respectively. | This article uses the convention JKLMNOPQR = LSLSLSLSL and pitch standard J = C4 = 261.6255653 Hz.

== Low harmonic entropy scales == | |||
The familiar harmonic entropy minimum with this MOS pattern is [[Meantone family#Godzilla|godzilla]], in which a generator is [[8/7]] or [[7/6]] (tempered to be the same interval) so two of them make a [[4/3]]. However, in addition to godzilla (tempering out 81/80) and the 2.3.7 temperament [[Chromatic pairs#Semaphore|semaphore]], there is also a weird scale called "[[Pseudo-semaphore|pseudo-semaphore]]", in which two different flavors of [[3/2]] exist in the same scale: an octave minus two generators makes a sharp 3/2, and two octaves minus seven generators makes a flat 3/2. | |||
