Some folks say that microtonal music sounds 'spicy.' Well 12edo is spicy too - you just get de-sensitized to its taste after over-exposure. But there is a way to experience 12edo again, to get a fresh sense of its character! You take a microtonal track that you're really familiar with, re-tune it to 12edo and listen through. I found that all tunings have a mood of their own, just like Ivor Darreg said. You choose a particular tuning to infuse its mood into your composition. I hope this video is a working demonstration of that effect.
