Guitars cover a wide range of instruments designed to suit different styles, techniques, and sounds, from acoustic and classical models to solid body, semi-hollow, and hollow electric designs. Factors like body shape, scale length, neck profile, string type, and pickups all influence how a guitar feels and responds, making each type suited to different players and musical approaches. Whether used for rhythm, lead, songwriting, or experimentation, guitars are expressive, versatile instruments that form the heart of countless genres and playing styles.
