What is herald's trumpet?

The herald's trumpet is a large, brass instrument that is often used in ceremonial occasions and in marching bands. It has a distinct, fanfare-like sound that is loud and attention-grabbing. The instrument is typically played by skilled trumpeters who have been trained in the art of heraldry and ceremonial music. Historically, the herald's trumpet was used by heralds or messengers in the royal courts of Europe to announce the arrival of important people or to signal the start of important events. Today, it continues to be used in military ceremonies, parades, and other formal events to add a touch of pomp and majesty to proceedings.
