Hearing Your Own Voice
Why does my voice sound different on a recording than in my own head?
When you speak or sing, you are hearing most of your voice via the vibrations travelling through your head, not sound travelling to your ears from outside. The sound waves that make up the sounds of your voice are travelling through a lot of bone, muscle and other tissues before they make it to the ear drum. Hence, it changes a bit, that's why every voice has a unique version that only its owner can hear.
How does this effect learning how to sing?
Sometimes you will make a sound that in your own head...
