This paper introduces a new compositional process based on transformations of previously existing material by segmentation of information located in a 2-dimensional cellular- space, the use of Walsh Functions as triggers, and recombinancy by cyclic transposition. The process can produce a wide spectrum of results depending on the size of segmentation, the choice of the Walsh functions, the operation(s) used, and the parameters entered for each operation. These results can range from a simple variation of the input, to an output, holding little or no resemblance with the original.23da Silva, P., (2003) David Cope and the Experiments in Music Intelligence, , http://www.spectrumpress.com/da-silvaweb-papers.htmlda Silva, P., (2005) Representation of Music in Cellular Space, , Los Angeles, CA: Spectrum Pressda Silva, P., (2005) Cellular Variations, , Los Angeles, CA: Spectrum Pressda Silva, P., (2005) Piano Solos I-IV, , Los Angeles, CA: Spectrum PressCope, D., (1991) Computers and Musical Style, , Madison, Wisconsin: A-R Editions IncBeauchamp, K.G., (1975) Walsh Functions and Their Applications, , London, Academic PressHall Jr., M., (1986) Combinatorial Theory, , 2nd Edition, John Wiley and Sons IncRozenberg, M., Microcomputer-controlled sound processing using Walsh Functions (1979) Computer Music Journal, 3 (1), pp. 42-47
