As much as people describe just intonation as pure, etc, at least in this example it just sounds wrong to me.
As far as I understand, just intonation requires instruments to be tuned differently for different keys and stops "working" if a piece strays from the key (which music from Bach's time will often do).
Equal temperament is our workaround for the physics which doesn't quite match the 12-tone system.
As far as I know, no one has so far made a piece using the Jintone instrument (it's admittedly quite clunky for actually playing rather than toying around), but there's plenty of music in the just intonation tuning system. To completement ivanmaeder's answer, and to counter balance the fact that most just intonation music tends towards experimental classical stuff, here's a chiptune game soundtrack mostly in just intonation: https://mayazimmerman.bandcamp.com/album/galactic-refugees-o...
