Oxygene, Pt. 4

Oxygène, Pt. 4 is distinctive for applying 18th-century Baroque harmonic structures (specifically the circle of fifths sequence common in Vivaldi or Bach) to 20th-century electronic synthesis. The harmony is strictly functional, relying on the tension and release of the ii°-V-i progression in a minor key. Unlike many pop songs that use 4-chord loops, Jarre uses a full 8-bar cycle that traverses the entire diatonic scale, providing a sense of 'narrative' and constant forward motion that complements the driving 'Popcorn'-style sequencer rhythm.

Jean-Michel Jarre composed the piece in his makeshift home studio using a variety of analog synthesizers. At the time, the project was rejected by several major record labels who believed an instrumental electronic album without a lead singer or traditional drums would not be commercially viable. Jarre eventually found support through Hélène Dreyfus and the label Les Disques Motors.

As the breakout hit from Jarre's landmark 1976 album, 'Oxygène, Pt. 4' transformed the synthesizer from an experimental curiosity into a mainstream melodic powerhouse. It is a cornerstone of the Space Music genre, blending hypnotic rhythm patterns with ethereal, layered textures.
