A brass wind musical instrument sounded by lip vibration against a cup mouthpiece. It has been made of horn, conch, reed, or wood, with a horn or gourd bell, as well as the modern brass instrument. The metal trumpet dates from the 2nd millennium BC in Egypt, when it was a small ritual or military instrument sounding only one or two notes. In the Late Bronze Age, it was made by riveting sheet bronze into the shape of a cattle horn.
