I saw this on Twitter recently and it made me laugh! I'm laughing right now!
As a choral director, I've been diagnosed with
Irritable Vowel Syndrome.
But rings true for so many choral directors :-) We most certainly DO get irritated, opinionated, and insistent when we share pronunciation and articulations with our choirs.
I once made a t-shirt with the following on the front:
Society for the Advancement of Vowel Unification in Choral Singing!
When I get home, I'll add a photograph of it.
