Linear Computer-Music through Sequences over Galois Fields
This is an incremental approach for electronic music composers, applying mathematical structures to automate composition.
The paper tackles automatic composition of monophonic electronic music using binary sequences derived from finite field structures, generating new compositions including a piece from the Lenna picture and scores like 'Between Lenna's eyes in C major'.
It is shown how binary sequences can be associated with automatic composition of monophonic pieces. We are concerned with the composition of e-music from finite field structures. The information at the input may be either random or information from a black-and-white, grayscale or color picture. New e-compositions and music score are made available, including a new piece from the famous Lenna picture: the score of the e-music <<Between Lenna's eyes in C major.>> The corresponding stretch of music score are presented. Some particular structures, including clock arithmetic (mod 12), GF(7), GF(8), GF(13) and GF(17) are addressed. Further, multilevel block-codes are also used in a new approach of e-music composition, engendering a particular style as an e-composer. As an example, Pascal multilevel block codes recently introduced are handled to generate a new style of electronic music over GF(13).
