A scale of chords may be used to set or read an angle in the absence of a protractor. To draw an angle, compasses describe an arc from origin with a radius taken from the 60 mark. The required angle is copied from the scale by the compasses, and an arc of this radius drawn from the sixty mark so it intersects the first arc. The line drawn from this point to the origin will be at the target angle. (Wikipedia).
An A chord is made from combining the notes A, C# and E

A more rational / integral Scale Notation | Mathematics and Music | N J Wildberger
Let's use our logical mathematical notation for the 12 tones of the chromatic scale to discuss various important scales that are found in a variety of cultures and idioms, including the major, minor, blues, pentatonic and Indian or uniform scales. But we have to let go of the unfortunate "

The fundamental scale is the chromatic 12 tone scale! | Maths and music | N J Wildberger
What is the most natural scale? Can we transcend our cultural indoctrinations when it comes to music and try to see the mathematical essence of things? And can we also move beyond the familiar musical thought patterns that the architecture of the piano (and to a lesser extent that of the g

Rethinking musical note naming from a mathematical point of view | Maths and Music | N J Wildberger
Let's step back a bit from our piano focused notation for naming musical notes, and adopt a more mathematical, logical terminology. This will have major advantages to our understanding of the structure of intervals, scales, modes and chords going forward. We use this notation to discuss th
