I am trying to get away from using the term "ethnic" woodwinds, one that I have used frequently in the past as a catch-all for the instruments I play that aren't modern Western woodwinds. The term was problematic from the beginning, since, for example, I was using it to include instruments like recorders, which fall squarely under the umbrella of Western music traditions, but are arguably period or historical instruments. Additionally, I find that the term "ethnic" increasingly grates on my ear as too ethnocentric and limited a view, and incompatible with my real attitudes concerning music from cultures and traditions other than my native ones.
