This sound-rich Web site explores the science of music, starting with the existential question: "Why does my voice sound so good in the shower?" The physics of how shower walls alter sound waves to affect volume, reverb, and bass boost is explained. Another big question: "Why does some music give me the goose bumps?" introduces the neurobiology of our emotional response to music. Other parts of the site look into the historical background of various extraordinary instruments such as the steel drum and the jembe.
