The Large interval in Lucy Tuning

Hi Charles,

Searching for information about Lucy Tuning both on your websites and in the past messages posted here, here is what I understood:

Assuming an octave is one complete revolution, the Large interval would use the radian angle.

If a Radian equals 2π, why does the Large interval uses its inverted form as 1/2π ?

A Radian doesn't equal 2π, is your answer.

A Radian is one revolution divided by 2π.

In degrees, that is 360/ 2π =

Although no-one (including me) seems to know why LucyTuning works so well;-)

You are right Charles, thank you! One circle or revolution has 2π radians, thus 1 radian is 1 revolution / 2π.

Beautiful radian explanation here:
