High Quality Content by WIKIPEDIA articles! The baritone guitar is a variation on the standard guitar, with a longer scale length that allows it to be tuned to a lower range. It first appeared in the classical music realm. The Danelectro Company was the first to introduce the electric baritone guitar in the late 1950s, and the instrument began to appear in surf music, as well as background music for many movie soundtracks, especially spaghetti westerns. In more recent history, the baritone guitar has found use within styles like rock, metal and improvised music. Some Baritone guitars may also have the capacity to be used as a bass guitar if strung correctly.
