In the summer of 1953, Karlheinz Stockhausen began composing his first piece of elektronische Musik at the Westdeutscher Rundfunk Studio for Electronic Music in Cologne. Up to that point, Stockhausen's only experience with electroacoustic music was his time spent at the Radiodiffusion-Télévision Française the previous year, where he assisted Pierre Schaeffer and composed a piece of musique concrète. An early case study in the marriage of serial aesthetics and electroacoustic techniques, Studie I is a rigorously organized work that reflects Stockhausen's compositional philosophy of a unified structural principle in which all musical materials and parametric values are generated by and arranged according to a single governing series. In spite of this meticulously wrought serial structure, Studie I displays features that are the consequences of the realities of electronic sound production either imposing on the sonic result, or altering the compositional plan entirely. I use a three-part approach to my analysis of Studie I by examining Stockhausen's serial system, the electroacoustic studio techniques in use in 1953, and the original recorded realization through spectrographic analysis. Using this methodology, I expose the blurring of the supposed divide between elektronische Musik and musique concrète by exploring the features that lie between the serial plan and the technical processes Stockhausen used to realize Studie I.
