@julesh - Yes, I've been taking a perhaps overly keyboard-centric approach in this talk. (It makes sense because you can't do everything in an hour, and I play the keyboard, as do a lot of theorists.) Violinists live in another universe. A good violinist will apparently use equal-tempered, Pythagorean tuning or just intonation depending on context!
I saw a good video about this yesterday. I find it a bit mind-boggling and can't help but wonder if they're faking it. But there are actually lots of videos about this, so if they're faking it they do so en masse.
