See Rowuk, I'm telling you we need to come up with a different term since bore size is so convoluted. Maybe a on line survey! Ask people what adjectives they use to describe trumpets with a small bore verses trumpets with a large bore and what trumpets they attribute this to. From there, devise a term. Damned I wish I knew how to put together an on line survey. --------- If any of you out there in cyberland are music majors and need a thesis idea or a doctoral student in search of a dissertation topic, here's a good one!
