Chord comes from a musical term, a combination of three or more musical tones sounding simultaenously, as well as a term used in geometery referring to a straight line between two points on a curve. It comes from Latin chorda via Ancient Greek khordḗ (string of gut; cord, string) from Proto-Indo-European *ǵʰer- (bowels). Chord is also a surname, perhaps a variant spelling of Cord, an occupational name for someone who was a rope-maker which also comes from the same source as Chord.
