Guitar tunings assign pitches to the open strings of guitars, including acoustic guitars, electric guitars and classical guitars, among others. Tunings can be described by the particular pitches that are denoted by notes in Western music. By convention, the notes are ordered from lowest-pitched string (i.e., the deepest bass note) to the highest-pitched (thickest string to the thinnest).
