All right right off the bat, I would like someone to make a song without any lyrics just background music. If you are wondering why I want this so bad its because I am making a film for my IB film in school and I started a horror movie and I needed horror music in the background it would be great if you can make several sound tracks. Also the fact that I can't use copyright music so I have to compose my own music.

'it would be great if you can make several sound tracks'

This is a HELP desk. I just don't see anyone volunteering to do your school work for you. It's a big job anyway.
There is music in the public domain that wouldn't be bad for a horror movie, such as organ music, but you are on your own finding it.
On the other hand, something out of the ordinary for a horror movie would be even better. Like opera, or Calypso, or a violin solo.

I'll never forget seeing 2001 for the first time, and hearing two pieces by two Strausses, The Blue Danube waltz and the symphonic poem Also sprach Zarathustra.
Totally unexpectedly weird, yet it fit. Kubrick was reminded of the movement of planets.
