Etymology: History and Origins of "Chord"

The word "chord" has a somewhat complex etymological history. The musical meaning derives from Middle English "cord," from the Latin "chorda," which originally referred to a string or the string of a musical instrument. This came from the Greek "khordē" with the same meaning. Interestingly, the spelling with "h" (chord) became standard for the musical sense to distinguish it from "cord" (a length of thin rope). The geometric meaning also derives from Latin "chorda," as early mathematicians likened a straight line across a circle to a bowstring. The emotional sense of "striking a chord" emerged later as a metaphorical extension of the musical meaning, suggesting that something resonates emotionally in the same way that musical notes vibrate together harmoniously.
