Answer:

The Erl-King, also called The Elf-King, dramatic ballad by J.W. von Goethe, written in 1782 and published as Der Erlkönig. The poem is based on the Germanic legend of a malevolent elf who haunts the Black Forest, luring children to destruction.

So the music will be dark, thin, slow and breathy. To portray the gothic and scary theme of the poem. I will compose the music with distant creepy movements and eerie haunting winds that are played in the background that will build up the spooky atmosphere. Sound effects that mimic human fear, including pulsing heartbeats and slow and heavy breathing, also increases the level of scariness.
