Dave - wasn't there some discussion several years ago about the neck angle changing on the Yani curved soprano at some point?
Seems like it....I'll have to do a search.
Discreet - it's the curves (both neck and bow) in the saxophone design that make it sound less like an oboe/bassoon, and more like a sax. It has to do with the internal accoustics, and how the sound waves bounce around inside it.
