Pitch is high, pitch is low -- and we'll use some singers you know (and a few you probably don't) to explore different pitches in the human voice.

This episode was recorded in part at Semple Elementary School in Louisville, KY. Thanks to music teacher Penelope Quesada and everyone at Semple for hosting us.
