How does a guitar make a sound? The sound of an acoustic guitar is created by the vibration of the strings. This vibration is then amplified by the body of the guitar, which acts as a resonating chamber. An electric guitar produces sound by using an electronic amplifier to amplify the vibration of the strings. The amplifier can also modify the guitars tone characteristics! At Arbutus Music, we have a teacher for every type of guitar and style of music!
