neat-o © Circle of 5ths thingy

Use this in your master-piecery.

What is the right panel for?

I don't understand

lol this is waaaaayyyyy over-complicating things.

What you are seeing there is a geometrical approach.

You have a circle with equidistant points that represent the notes in 12TET. A note is assigned to each point, and each point is one fifth away from the next one. Ok, you have now a ring.

Inside that circle, you can inscribe polygons. Each polygon is a set of notes (that you can put in a specific order to get a mode of a scale). That polygon is a structure. The magnitude of each side of the polygon is given in fifths (counted clockwise).

That big polygonal structure can be divided into smaller substructures, which are also polygons.

So, what is a polygon in this system? Pretty much anything. It can be a big set of notes that maps to a scale (say a chromatic, and that polygon can be a structure). It can also be a set of 3 notes that you can map to a triad (this polygon would be a triangle; a square can be a chord with 4 notes; a pentagon can be a chord with 5 notes, a different pentagon can be pentatonic scale... ).

That little app allows you to find polygons inside other polygons: substructures inside a bigger structure.

You can find all "substructures" that map to all the minor seventh chords within a "structure" (as in, what minor seventh chords is it possible to find in that set of notes). You can find all pentatonic scales found on a chromatic scale...

That's pretty much it, a geometrical approach to represent and search for subsets (that you can rearrange into scales or chords or whatever).

ya exactly. Like maybe one section of a progression goes through a chord with a base note of each of the first outer polygon, and the second uses the inner one.
