And Time Here Forked

This is “The Castle” from Machinarium. The composer is Tomas Dvorak. In 2009 he discussed this track with an interviewer:

The song is in two parts. One is more rhythmical, with these concrete instruments (the pizzicato from the string instruments). Later, in the second part, it’s collapsed into more ambient stuff, but you can still hear the melody from the original part through the granular effects. It’s derived from the original tune, like maybe if you went to sleep and heard it from a dream. They’re like different faces of the same tune.

The phrase is exposed in different interpretations through the sound. I like this kind of approach.
