'''5ed100''', '''the stellar magnitude tuning''' or '''5 equal divisions [[Ed100|of the double decave]]''', is an equal-step tuning with each pitch being about 2.512 times larger than the other, the number known as the Pogson's ratio. | |||
== Theory == | == Theory == | ||
The tuning is pretty meaningless as far as pitches go, since there's only 7-8 steps of it in the entire human hearing range, but it has a real life equivalence to astronomy - each step of it is known as the Pogson's ratio and it has an application of being the factor which sets two stars being 1 magnitude apart. This means subdividing it makes a meaningful major tenth of 1594.525 cents. | The tuning is pretty meaningless as far as pitches go, since there's only 7-8 steps of it in the entire human hearing range, but it has a real life equivalence to astronomy - each step of it is known as the Pogson's ratio and it has an application of being the factor which sets two stars being 1 magnitude apart.
