After fourth-grade scientist Curious McCarthy observes her dad fixing their doorbell, she starts to wonder about the science of sound. Meanwhile at school, it's time for Curious to pick an instrument for band. Curious chooses the flute, but the band director says Curious's lips are all wrong for the slim woodwind. Can that be true, and if it is, can science help Curious find her perfect instrument? A sound-related science experiment will have readers putting the story into action, while a glossary and reader questions support the text.
