If you've ever sang in falsetto, you know that your throat is between your voice and your mouth. In a standard voice, you sing from your belly. And when you sing in a falsetto, you're blocking that. It gives it a filter. It gives it a character. It's less revealing.
As a body in a world, here is our choice: we can be more loving or less loving. That's it. We can relax as the entire moment's show of love's swirl, feeling open as all--a vicious rainstorm, tweeting birds, our lover's lips, a sense of worthlessness-- or we can close to some aspect of experience, pulling away as if we were separate.
