Why are fanfares played on brass instruments?

Fanfares are traditionally played on brass instruments due to their powerful, bold sound and ability to project over long distances. Brass instruments, such as trumpets and trombones, produce bright, resonant tones that command attention, making them ideal for announcing important events or ceremonies. The clarity and richness of brass can convey a sense of celebration and grandeur, enhancing the ceremonial nature of a fanfare.
