Imaginary Landscape No. 4: study and annotation of the score

This paper presents a study of the score of John Cage’s Imaginary Landscape No. 4 for 12 radios and 24 play- ers. After introducing the work and its history, the paper shows the relation between the formal operations at its origin and the final score. An annotation format is then introduced, and the resulting annotated version of the score is discussed. The latter may be used as an analytical tool, as a performing aid for human players, and as source data for an automated realization of the work. Finally, a complete graphic score is presented, obtained from data processing and displaying.
