concert

The word "concert" has a fascinating journey from a concept of mutual agreement to a public musical performance. It originates from the Italian concertare, meaning "to bring into agreement", which itself derives from the Latin concertare, "to contend, dispute, or fight (with)", a compound of con- ("together") and certare ("to contend, decide", from certus, "sure"). The semantic evolution moved from the idea of a strenuous effort or contest to one of harmonious cooperation and mutual settlement. By the late 16th century, it entered English describing agreement in purpose or action, and by the mid-17th century, this sense of harmonious union was applied specifically to a harmonious union of voices or instruments in a musical performance.
