Like a theremin doing an impression of a car alarm

I thought someone in the neighborhood was playing the saw. Then I realized it's Olive exploring the highest pitches of her voice.
Sounds like a theremin doing an impression of a car alarm.
I'm outside and it's pretty loud even though she is inside on the third floor. It must be coming up from the vents. lol I love when she sings covers of heavy metal songs. Olive makes Judas Priest sound like a Disney movie.
