Nellie after the first time it gets so much easier. I used to hate being in the front row, let alone singing on my own, but after a while you think nothing of it.
My breathing isn't perfect by any means. Last week I got picked on by our new conductor, my diaphragm was displayed and discussed and this week, I thought - floaty tunic time! Thank heavens, it worked, and another poor soul was used as a teaching aid. But I have to say, it and the exercises worked and it's easier to hold long notes as a result. Which in turn leads to less public humiliation.
One of our Christmas concerts is going to be all british pieces with british place names in, if anyone can think of any with a place or county name in either the piece or the title? There are various wassail songs, but mostly variations on the same tune with varying place names, and the Coventry carol, that sort of thing.
