It was a while since we wrote that! Here’s the paper: [https://zenodo.org/record/1193251#.YAXDrFP7Q-U](https://zenodo.org/record/1193251#.YAXDrFP7Q-U)

I haven’t looked at it for a while but I remember thinking at the time that it didn’t get as deep into patterns as I’d have liked.

I’d forgotten about considering ‘composition’ and ‘interference’ are such different categories, I guess they’re closely related? The [Laurie Spiegel paper](https://forum.alpaca.lurk.org/t/reading-2-laurie-spiegel-manipulations-of-musical-patterns-and-others/195/3) which we read offers a different way of categorising things.

Conditional jumps and a lot of transformations could be considered in terms of symmetry, e.g. reflection, rotation and so on. Maybe not all the transformations can though. When it comes to thinking about the individual transformations in something like [tidal](https://tidalcycles.org/), they don’t necessarily conform to these levels, usually there’s multiple things going on at once, so I haven’t found these 'level’s have much descriptive power… But maybe that is indeed because the levels aren’t well developed.
