The sound waves from the strings of an acoustic guitar resonate through the guitar's body, creating sound.

5. An electric guitar is a fretted stringed instrument with a neck and body that uses a pickup to convert the vibration of its strings into electrical signals. The vibration occurs when a guitarist strums, plucks, fingerpicks, or taps the strings
