Like, concretely: Lately I've been fascinated with JI beyond the restrictions of periodic scales. If I'm synthesizing without a keyboard then do I care how well 31EDO approximates 5/4. What does good voice leading look like in JI. Do prime harmonics play a part in neo-Riemannian transformations. What does the singer's formant do with choral overtone clusters. How much trouble is an 81/80 comma really in the face of a funky detuned chorus supersaw.
Can I train my ear to just know this stuff.
