I have an idea for a data visualization, and on the x-axis I want to plot a linear sequence of musical keys (if possible).
If it's only major keys, then it would be something like
C C♯ D D♯ E F F♯ G G♯ A A♯ B
But if I want to include minor scales, for example, C minor, would that make more sense before C major, or after C major?
Another option is to put it as a duplicate x-axis, in the same column as E flat major, which is essentially the same scale.
Are there any similar datavizzes that I could use as a precedent?
