Maddie visits a singing group and the children help us find out how we use our mouths, vocal chords and lungs to make different sounds when we sing and speak. Maddie uses a special machine to measure the different high and low sounds that we make. Next, she visits a trombone factory to see how copper and zinc metals are made into brass trombones.
