I keep a guitar on the bed, so if I wake up in the night I can easily reach for it, strum and sing a tune or three.
I wrote a Song, singing it while lying on my back. Imagine the positioning of my vocal cords.
The notes were sustained at the ends of Lines, and the vibrato was gentle and well-executed.
Sitting up, trying to achieve that same vibrato quality, I found I could not, without concentration and practice.
The positioning of the vocal cords, in relation to each other, in relation to gravity, changed the physical dynamics of the vocal execution.

There will always be another song to be written. Someone will write it. Why not you? www.garyeandrews.com
