A baritone guitar is a type of guitar with a longer scale length, typically a larger body, and heavier internal bracing, so it can be tuned to a lower pitch. It is a 6-string, long-scale guitar, sporting heavier strings and meant to accommodate a lower range of notes. The standard baritone is typically tuned B to B, which is a perfect fourth lower than a standard 6-string guitar. Baritone acoustic guitars typically have larger bodies than standard guitars, and have longer scale lengths so the strings can be tuned lower while remaining at normal tension. Baritone guitars have been used in various genres of music, including rockabilly, surfing, and metal. They are known for their ability to produce different voicings of the same notes found on the standard tuned guitar.
