The Sound of Music
“Do, a deer, a female deer, Re, a drop of golden sun. Mi, a name, I call myself…. “ What does that mean? Have you ever wondered what sound is and why some sounds can be obnoxious and others can be melodious? Sound, maths and physics are intricately related. Indeed, our favorite mathematician, Pythagoras, discovered the ratio connecting different musical tones to lengths of a string. The wavelengths, amplitude and frequencies of sound waves relate the different characteristics of sound, and many different sounds can be created in different ways.
In this project we will explore the physics and maths of sound to the extent that we can then create our own musical installations. Sound makes up music. The source of all sounds is vibration, and vibrations are simply little zones of compressed air. This air pushes against the air around itself which pushes that air and so forth. This combination of compressed air and refraction of matter produces longitudinal waves or sound waves. A vibrating source that produces rhythmic variations in the air pressure is the source of sound waves.
