Baritone guitars are designed with a longer scale length than standard guitars, allowing them to be tuned lower while maintaining string tension and clarity. They typically sit between a standard guitar and a bass in pitch, producing a deeper, heavier sound without losing definition.

They are widely used in alternative, metal, ambient, and cinematic styles, as well as for modern rhythm work and textural playing. Baritone guitars offer tight low-end response and extended range, making them ideal for players who want lower tunings with improved note clarity and control.
