@PaavolaPyry no one knows how to read a CSound score, so don't feel bad.š
But, basically what it does is create a series of instructions that the computer interprets into music.
You bring up an important point, the use of parallax. So, when you ride in a train and see objects passing in 2 dimensional space, you see the objects closer to you move faster than the objects in the background. Music, can create this sense! The concept is simple to have a melody, or fugue in the case of "Seraphim," move faster than the background ambient music.
The music is very discomforting, I'll admit, but CSound is such a new medium that anyone is throwing all they have at it to create a composition. It's come a long way since beeps and boops. The fluid design of the medium, large amounts of oscillation, and sound manipulation are what draw many composers to the medium.
Here is my first CSound composition:
Notte Splendida Notte | Astronomy 2009
It blends the opera singer with the medium to effect, icy cold with the passion of the voice in creating a composition. It's a little easier to listen to.
