After studying John Coltrane's wholetone/chromatic circular diagram, I was determined to make a program to show musical intervals around a circle. And if I could, to make a concentric "inner" ring with note offsets, like Coltrane did. So the weekend arrived and I got busy...
Like many music theory minded people, who also are into jazz, I have seen and wondered about John Coltrane's curious circle drawing...
Previously, I figured out how to "fingerprint" songs with radar charts. But as soon as I did, I wanted to analyze the entire set of tunes by well known bands like Led Zeppelin.
I stumbled across this link with this cool chart.
