A trumpet is a musical instrument. It is the highest register in the brass family. Trumpets are among the oldest musical instruments,[not in citation given] dating back to at least 1500 BC. They are played by blowing air through closed lips, producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century they have primarily been constructed of brass tubing, usually bent twice into a rounded oblong shape.
