I used to have people in choir who either would kill to stand next to me if they were singing my part (alto-I’m a mezzo) or speak to the choir director in private to be moved as far away from me as possible.
It’s hard to blend when you have an operatic type of voice and you’re singing with regular singers. I’d have to work hard not to stick out, but sometimes the director would beg me to because no one else knew the part!
I never took it personally-never had any attitude. People always expect you to, but they have to have as much fun singing as I do, so if they want to move, I don’t mind.
