I do so envy those who can sing, and realise my voice is quite weak now that I'm 68, because I rarely sang, and never after the age of about 9. I had a bad abcess in my right ear when I was 5, and this has left me slightly deaf, and also with no tolerance for loud music. I was young in the 70s but never entered a disco because my ear could not handle it. I also cannot tell direction of sound.
At junior school I was belittled for singing out of tune, so I learned to mime. At home, Mum said I could sing as long as I did the vacuuming at the same time. At grammar school the music teacher, Doc Wood, could tell I was miming and tried to force me to sing. I was generally a good girl, but I dug my heels in and refused. Detention was the better option than humiliation. After that, I always took the seat behind the piano where he could not see me. Later I fell out with a boyfriend who wanted me to join in the Christmas carols, and would not believe I was incapable.
So when I listen to any music, choirs, soloists, opera etc I have rather more admiration than most. They do so well, that which I cannot do at all.
I have heard that absolutely anyone can be taught to sing. I wonder if this is true? I suspect not, though I have to admit that no-one actually ever tried to teach me.
