Have you ever thought about how cool it would sound if every single chord was tuned in perfect JI? Instead of just tuning every note of the scale once and then running into temperment issues when, for example, moving from the tonic to any other chord in a given key, you would adjust the tuning for every single chord in post? I usually think about this for a second and then immediately think of how stupidly tedious it would be to actually accomplish this. Interesting to think about, though, don't you think?
