I once took a year of oud lessons, and the nuances in microtonality really blew me away. There were all sorts of things in the aural traditions, like scale X having a fractionally sharper 3rd ascending than scale Y, but with both notated in the same way. But a lot of the larger subdivisions (i.e. quarter tone sharp/flat notes) were surprisingly natural to learn, and no different to semitones (from a listening/playing perspective) after a while.
