What section does the tin whistle fit in? Oh yes, that's right, the pretend section! Has to be woodwind too though, right?
So are you telling me that a euphonium is NOT a brass instrument and is not a wind instrument? IT IS NOT MADE OF WOOD!
I am telling you that a euphonium is a brass instrument and NOT a wind instrument. Having played one for over 40 years, both professionally and for fun, I might have a small idea about this A Brass band is made up of brass instruments only, a wind band has those horrible squeaky things in it as well.
I won't and can't argue with your professional expertise, but this seems to be a contradiction. Anyway what started out as a bit of fun seems to have attracted the pedants, not what I had in mind or expected! Not bothered about the "ecky thumps", brass bands are not my thing!
