Hendrix, Cobain and Page. They can all shred, but how exactly do the iconic contraptions in their hands produce notes, rhythm, melody and music. When you pluck a guitar string, you create a vibration called a standing wave. Some points on the string, called nodes, don't move at all, while other points, anti-nodes, oscillate back and forth. The vibration translates through the neck and bridge to the guitar's body, where the thin and flexible wood vibrates, jostling the surrounding air molecules together and apart. These sequential compressions create sound waves, and the ones inside the guitar mostly escape through the hole. They eventually propagate to your ear, which translates them into electrical impulses that your brain interprets as sound. ...
