Rainbow Music  Measure

Measure

The chart simplifies and unifies the relationship between proportion in math and music but also much more. It brings together 3 constants in Pi (π), Radian (c), Phi (Φ) in a simple to use way, leveraging only one factor (432) and just two math functions (division and subtraction).

The chart title has been selected carefully “Measures” to reflect the true nature of the breadth and depth of its application.

As all these constants are irrational numbers, irrespective of how they are written they are approximations (~), with resolution or scale being the remaining question, which is relevant to application.

This chart is supplied in High Resolution Adobe PDF.
