Today’s post uses a Csound function table to make trills and slides. At any given time, the notes can either be played straight, trilled up to the target, from the target to the next note, slid up to the target, or down to the target note. This makes for some frantic movements at first. This is just a few measures of one chord, and there are 35 in Amazing Grace.
Here’s the code for a trill up 16 steps in 72 EDO, which is a good approximation of a 7:6. The trill is 8 times up and down.f 457 0 256 -7 1 16 1 0 1.1665290 16 1.1665290 0 1 16 1 0 1.1665290 16 1.1665290
