From time to time I've thought about using 432 tuning but I always discard the notion because almost no one else does. It's at the front of mind again, because now I've started working with someone who favors it. So, I'm wondering...do you use, or have you ever used 432 tuning? If yes, what do you think of it in general? Is it as wonderful as some say it is? Pros and cons? Cons, I assume, mainly consisting of being out of tune with everyone else. And finding tuning tools (a tuning fork isn't going to work...is it?)
