It's music to your ears--but why does one instrument make a different sound than another? What separates music from noise? Why can we physically feel the beat of a big, bass drum in our bodies? And, how do we hear tone and rhythm? Uncovering the answers to these questions is a symphony of fun, and an entertaining way to understand physics and math! Each of these safe and "sound" experiments--delightfully illustrated with lively, colorful pages filled to bursting with photographs, drawings, and cartoons--uses ordinary materials to teach fabulous facts about the bangs, slaps, whistles, claps, and harmonies in our world. Study sound waves; play with changes in pitch; confuse the brain into thinking you're hearing something when you're not; and test out your vocal chords. Entertaining to look at and enjoyable to do!
