We always wander about where the sound of the guitar comes from and how it changes at different levels. When we take a closer look at the mystery, we can find out the answers.
A standing wave, as well as a vibration, is created when you pluck a guitar string. Then the vibration translates through the neck and bridge to the guitar’s body. With the together and apart of the air molecules, a sound wave comes to you. The frequency at which these air molecules vibrate is equal to the frequency of vibration of the guitar string.
As the frequencies of sound vibrating in various pitches, our brain accept it diversely. Four things affect the frequency of the vibrating string: the length, the tension, the density and the thickness. Guitars vary from each other in thickness and density. Thicker strings produce lower notes. Theses notes determine the pitch of the waves, which called overtones, and combine to form a complex wave with a rich sound. The different way you pluck the string lead to different overtones you get.
If you pluck the guitar at different parts of it, you can get odd and multiple overtones. Different guitarists have different physiologies of their hands. Following the various shapes and materials of guitars, the vibrations are changing. Electrical guitars share the same work principles, but they
Can process the wave in various ways, creating effects that make people enjoy the sound experience.
