Electronic Music and Generative Remixing: Improving L-Systems Aesthetics and Algorithms

Abstract

Postmodern art theories, overproduction, and digital technologies are testing the creativity, innovation, and social and political engagement of art. One Dadaist solution being explored by artists is the aesthetic possibilities associated with the conceptual process. For example, in the field of electronic music, producers and DJs are claiming that remixing is a genuine example of such a creative procedure; however, to justify this claim, remixing requires the bringing of the aesthetic foundations together using digital tools. The main problem is that digital audio workstations and plug-ins enclose artists in specific frameworks that blur the boundaries between true creativity and a perception of creativity. This article sought to develop remixing codes and software using Lindenmayer systems (L-systems), which are parallel rewriting systems with a type of formal grammar. As much of their potential remains unexplored, some algorithms and interface designs were developed to improve their interactive programming options. Finally, using the programmable L-systems as a genetic metaphor, some additions to musical morphing were developed as a starting point to building a generative remixing technique.

SIGraDi 2022. Critical Appropriations

“…Papers about computational creativity, generative art and parametric design show that the potential of shape grammars is not fully developed (Roncoroni, 2022). Besides, there is a lack of friendly and interactive generative 1 See https://investigacion.pucp.edu.pe/grupos/gries/noticia-evento/concurso-anualproyectos-investigacion-cap-2021/ applications.…”

“…In existing applications, rules are rigid, they can't share parameters and programming tools like loops or conditional statements. In previous research (Roncoroni, 2022), improvements were developed to L-Systems dictionary and rule sets, to overcome some of their limitations. I will mention here just one of these extensions: automatic symbols ("n") with nested recursion and with slave or sub-symbols ("ñ") controlled by the number of instances, or the master symbol hierarchy in the grammar, or by the level of the substitution process.…”

Electronic Music Signal Denoising Method Based on Naive Bayes

“…Electronic music includes a lot of unconventional Musical Instruments produced by the electric sound, prefabricated recording and then edit a variety of environmental sound, rely on electronic oscillation circuit as the working principle of synthesizer music, as well as modern computer composition system produced virtual digital music [1]. The traditional research is limited to music itself, and the research on music audio only focuses on the field of acoustics.…”
