It always surprises me when singers sing so loudly that they can’t hear the rest of the choir.
It’s hearing the other harmony parts that keeps you on the straight and narrow, and it’s where the singing pleasure lies.
I came across a choir doing an outdoor performance recently.
They were really good, but were let down by the balance between backing tracks and the voices.
I’ve written before about How to know how loud you should sing in a choir.
But as a choir member you are working as part of a team, so it’s not entirely up to you. It’s all about balance.
