> aleatoric music composition

You made me look 'aleatoric' up just now ("a process is said to be aleatoric ... if its course is determined in general but depends on chance in detail" per Wikipedia), but all I found was stuff I had heard of a long time ago, in that you can generate various types of music randomly and a reference to a very old dice game attributed to Mozart.

So I'm left wondering how this generator would be more useful for generating random music than ordinary dice or a RNG?

Perhaps aleatoric is the wrong word... I imagine that you could overlay the ghost diagrams on grids, follow the tiles (as if traversing land on a map), and your paths would produce melodies. There are hex-based musical keyboards (search for "hex keys" on Google or YouTube), so every position would be assigned a specific pitch. You could expand this concept to generate note lengths, rests, key changes, timbral effects, etc.

That's one way to implement it. All of the generative music algorithms I've seen have been very limited, and have produced one specific flavor of music. Seeing all these amazing patterns in the ghost diagrams, I wonder if there's a clue to generating more diverse/expressive music lurking within this system. (Emergent behavior?)
