Go To

Horns are among the oldest, and loudest, musical instruments. Their ability to be heard over the din of battle gave them a key role in many historical armies, and their descendant the bugle is still used in this way today. This association means that horns in fiction often have strong symbolic links to warfare, leadership, defiance, and destruction.

    Horns of Summoning 

These horns are used to rally demoralized soldiers, to bring people to a central meeting place, and when Gondor Calls for Aid. If the soldiers are too far away to be helpful, horns can call out the peaceful townsfolk to form the Home Guard. In fantasy settings, they may be Summoning Artifacts that unseal a Sealed Good, Evil, or Army in a Can.

Real Life

  • In Judaism, the shofar is a ram's horn blown during the Rosh Hashanah and Yom Kippur services to inspire awe and repentance.

    Horns of Destruction 

These horns are bad news. In fantasy and mythological contexts, the horns themselves cause destruction and death when sounded. In more realistic settings, they cause dread to those who hear them. There's some overlap with the first type of horn, though—a horn that successfully rallies an army means the other army isn't likely to fare so well. Compare Musical Assassin.
