title: Harmony
context: The term harmony derives from the Greek ἁρμονία harmonia, meaning "joint, agreement, concord",[4][5] from the verb ἁρμόζω harmozō, "(Ι) fit together, join".[6] In the past, harmony often referred to the whole field of music, while music referred to the arts in general. In Ancient Greece, the term defined the combination of contrasted elements: a higher and lower note.[7] Nevertheless, it is unclear whether the simultaneous sounding of notes was part of ancient Greek musical practice; harmonía may have merely provided a system of classification of the relationships between different pitches. In the Middle Ages the term was used to describe two pitches sounding in combination, and in the Renaissance the concept was expanded to denote three pitches sounding together.[7] Aristoxenus wrote a work entitled Harmonika Stoicheia, which is thought the first work in European history written on the subject of harmony.[8]
