Place it at the very start of an edit as the opening signal, before any dialogue begins. Follow it with a bass drop sound button for a modern trailer hit, or finish a heroic reveal with clapping to sell the crowd reaction.
About this sound
This clip is a long, deep horn blast lasting just over thirty seconds, with a low resonant call that builds like a signal across a mountain hall. It feels grand, tense and triumphant, made for a serious announcement. It takes its name from Erebor, the dwarven kingdom in The Hobbit films.
