There is another side to this too - part of my music practice is the construction of instruments. Sometimes these are general (witness Islands for Norns) but other times they are not - I made a grid based instrument for the Patricia Wolf disquiet junto. It was an instrument - I had to learn to play it once I’d made it but it was certainly very specific to what I wanted to do with the track. I guess the reality is that that line is hard to find and almost certainly moves about for different people.
This feels like one of those things that as you look in more detail it becomes more slippery
