Movie trailer music is often epic music. Epic music meets all the requirements of trailer music, however, it often has added elements such as great percussion and also certain orchestral glissandos that make the music have a lot of dynamics.
The elements that cannot be missing in the epic trailer music are the soft beginnings with certain spaces to accommodate the trailer narrator.
The music should grow little by little as the trailer progresses with the film’s images.
We can say that epic trailer music should have an apotheosis, a knot and an apotheosis denouement.
