So can you just stop on a dime and hit those whistle-register high notes?
Sometimes I wake up and that's the easiest thing for me to do. Because I'm still kind of raspy. [Purrs in soprano] I like to do that.
It cleans out the pipes?
Yeah. But sometimes, when my middle register is more clear, those notes are harder to hit. I have a three-dimensional vocal cord situation. The breathy voice is its own thing. It requires a certain amount of sleep.
