what classical song at the end of the movie?

I think we where all too traumatised to hear a classical piano song, never mind its composer.......

Yeah agreed we were all too busy looking for the lost storyline to notice that music even featured in the film!

I would like to know the answer to this too...S

I definitely noticed the music, both the composed score and the classical song were great I thought. The classical composition was Frederic Chopins Prelude No. 15 in D-Flat Major, Op. 28, "Raindrops" It's a very powerful piece, and fitted perfectly in Prometheus.

Sepruda - thanks for the input!

Sepruda, thank you! for the others, the song started at the closing credits. I read that mr. Ridley Scott uses more often 'classical songs' in his movies. apparently, this is another example. I found it soothing to hear this song.
