Okay, so for some set M, at the value i to the power of -1 the change is equivalent to -a (presumably an arbitrary constant) times the sum from n = 1 to some arbitrary N the set D at some value i with n evaluated to a boolean. Idk why that’s neccessary since an upper bound is established. Or maybe that symbol means something else…
Anywho within that sum there is another sum where j is summed for every instance in which it is an element of the set C with some parameter i. And then the rest is just nothing.
But if Richard was just trying to be complicated and the equation means nothing, he could have used multiple indices on the sums, that gets really complicated, really fast.
Do you think the equation has something to do with the song, like M is each sequence of Fourier nodes for the beats and delta M is the change in pitch?
