This is an example of minimal techno; here the focus is on slow, subtle changes, primarily to the nature of the sounds themselves, rather than to the notes and rhythms.

But combining (or harmonizing) the melody with some chords helps to fill out the texture. This is an example of a simple chord progression: a series of chords played in a particular order. In many types of music, chord progressions are used to create a sense of tension and release, by moving away from the tonic of the song and then back again.

  A pre-chorus is a section that serves as a kind of link between a song’s verses and its choruses. In this song, each pre-chorus helps to build a sense of tension and energy that leads into the chorus. Each of the three eight-bar pre-choruses in this song has identical lyrics.
