In The Lord of the Rings: The Fellowship of the Ring, what instrument does Boromir blow at Amon Hen?

In The Lord of the Rings: The Fellowship of the Ring, Boromir blows the Horn of Gondor at Amon Hen.

The horn is Boromir’s distinctive symbol and is associated with his role as a son of Denethor, Steward of Gondor. In the film, its sound signals danger after Boromir tries to take the One Ring from Frodo and later defends Merry and Pippin from Uruk-hai.

Boromir blows the horn repeatedly while fighting, allowing the separated members of the Fellowship to hear that he is in trouble. Aragorn reaches him, but Boromir has already suffered multiple wounds from the Uruk-hai leader Lurtz.

The film presents the horn as a powerful warning instrument rather than simply a decorative prop. It helps connect Boromir’s personal fate with Gondor’s military identity and becomes one of the clearest audio motifs in the first film.
