The history of algorithmic composition using a digital computer has undergone many representations—data structures that encode some aspects of the outside world, or processes and entities within the program itself. Parallel histories in cognitive science and artificial intelligence have (of necessity) confronted their own notions of representations, including the ecological perception view of J.J. Gibson, who claims that mental representations are redundant to the affordances apparent in the world, its objects, and their relations. This review tracks these parallel histories and how the orientations and designs of multimodal interactive systems give rise to their own affordances: the representations and models used expose parameters and controls to a creator that determine how a system can be used and, thus, what it can mean.

The challenge of composing both sound and moving image within a coherent computer-mediated framework is addressed, and some of the aesthetic issues highlighted. A conceptual model for an audiovisual delivery system is proposed, and this model acts as a guide for detailed discussion of some illustrative examples of audiovisual composition. Options for types of score generated as graphical output of the system are outlined. The need for extensive algorithmic control of compositional decisions within an interactive framework is proposed. The combination of Tabula Vigilans Audio Interactive (TVAI), an algorithmic composition language for electroacoustic music and realtime image generation, with MIDAS, a multiprocessor audiovisual system platform, is shown to have the features desired for the conceptual outline given earlier, and examples are given of work achieved using these resources. It is shown that ultimately delivery of new work may be efficiently distributed via the World Wide Web, with composers' interactive scripts delivered remotely but rendered locally by means of a user's ‘rendering black box’.

SummuryIncreasingly diverse and complex computer-based support underlies critical human processes, such as education, commerce, medicine, science, defense, and government. These systems are fed massive amounts of data and due to the complexity and size of these systems, they are integrating and interfacing with each other with less human oversight. Soon, they will need to build, refine, and elaborate their own models and processes, making more decisions about what information to use in what manner and how to approach problems or goals. Hence, these systems must be able to reason about and report out to us their modeling and processing choices in order to help us monitor and control their operations and interactions. In this paper, we discuss our work on creating reflective systems, and how reflection coupled with “generative processes” and “cognitive instrumentation” will help enable organic computing systems. We then briefly describe our testbed for studying self-conscious modeling.

Artificial intelligence researchers and artists have trained machines and generative processes to produce visually interesting and novel works, thereby devising machinic means of creativity. At Artrendex, Playform was developed as an easy-to-use program specifically to be used by a broad range of artists, from beginners to those with advanced technical skills. This essay focuses on the motivations behind the development of Playform and the early reception and use of it by some artists. Our aim is to better understand both human and machine-based creativity at their intersection in an art generating system such as Playform.

Background, objectives and methodology of the research. The social and cultural paradigm of the 20th century has given rise to a type of composing thinking that did not exist before – a scientific one. Thus, the evolution of the composer’s writing can be defined as a path from thinking by perfect consonance, emancipated dissonance to thinking by deterministic sound and its parameters (height, duration, dynamics, timbre, and articulation). The term of the «composer’s writing technique» means a set of techniques and methods of working with the musical material as a result of the activity of thinking/awareness. Therefore, the aim of this article is an attempt to explore the relationship between the compositional process and writing techniques of the 20th – 21st centuries (pointillism, aleatorysonorous, algorithmic composition), as well as the specifics of polyphonic, homophonic writing in a new context. The methodology of the study includes references to the scientific works by P. Boulez (1971), K. Stockhausen (1963), V. Medushevsky (1984), M. Bonfeld (2006), I. Beckman (2010), I. Kuznetsov (2011), K. Maidenberg-Todorova (2013), M. Vysotska and G. Grigoryeva (2014). Presentation of research results. The phenomenon of writing techniques is very important in the study of the specifics of the compositional process, as it is the technique, for the most part, becomes the goal of creation for many composers of the 20th century. In addition to new techniques, polyphonic and homophonic writing have undergone some changes. The polyphonic one has specific features that are manifested in linearity, part-writing, etc. Examples can be found in the works by D. Ligeti (micro-polyphony), R. Shchedrin, V. Bibik, V. Ptushkin, V. Sylvestrov, and O. Shchetynsky. Regarding the homophonic writing, we shall note that, first of all, it is an indicator of style and conceptual thinking of a composer (works by A. Pyart, J. Tavener, and L. Sumera). In pointillism, the sound is thought of as a deterministic, isolated structure, which is expressed by its various parameters. Here are the examples from the creative work by A. Webern («The Variations for the Piano»; «The Variations for the Orchestra»), by E. Denysov «DSCH». The aleatory-sonorous technique is associated with the operation of timbre sonorities, according to their specific patterns, and developed in the 50–60s of the 20th century in the works by I. Xenakis, V. Lyutoslavsky, Ksh. Penderetsky, and D. Ligeti. The algorithmic composition is an indicator of scientific and mathematical thinking, and is divided into: fractal, stochastic, spectral, concrete and electroacoustic music. The first was formed within the framework of the works by C. Dodge, G. li Nelson, D. Ligeti, and others (I. Beckman, 2010). Stochastic music is associated with the name of I. Xenakis, and the ancestors of the spectral school are the French composers G. Grisey and T. Murray. Conclusions. The article considers the writing techniques of the 20th–21st centuries as components of the compositional process. It can be concluded that the studied techniques are fundamentally interconnected, revealing the nature of the composer’s thinking/consciousness from different positions. The presented techniques are: the objectification of sound forms, the method of creation; the fact of the composer’s consciousness; the consequence of the historical and cultural evolution of the musical language and communication.

The term “hypo-egoic” can refer to a variety of cognitive states, ranging from internal experiences of meditation, hypnosis, or spirituality, to overt acts of forgiveness or altruism. This chapter reviews the nascent literature on the neuroscience supporting such states, aiming to provide a more unified neural account. For parsimony, research findings are framed in terms of implicated brain networks, with particular attention as to whether networks are modulated to directly inhibit of egoic processes, or to generate competing, experientially salient, hypo-egoic states. The chapter concludes that hypo-egoic processing is not purely inhibitory in its neural architecture but often incorporates generative neural representations, enhancing sensory awareness in meditation and hypnosis, the theory of another’s mind in love and forgiveness, and vicarious enjoyment in altruistic acts. These generative processes may anchor attention and attenuate prepotent tendencies toward egoic thinking, allowing for the transcendence of self-concern in favor of some greater good.

Wu 無 is one of the most prominent terms in Ancient Daoist philosophy, and perhaps the only term to appear more than Dao in both the Laozi and the Zhuangzi. However, unlike Dao, wu is generally used as an adjective modifying or describing nouns such as “names”, “desires”, “knowledge”, “action”, and so forth. Whereas Dao serves as the utmost principle in both generation and practice, wu becomes one of the central methods to achieve or emulate this ideal. As a term of negation, wu usually indicates the absence of something, as seen in its relation to the term you 有—”to have” or “presence”. From the perspective of generative processes, wu functions as an undefined and undifferentiated cosmic situation from which no beginning can begin but everything can emerge. In the political aspect, wu defines, or rather un-defines the actions (non-coercive action, wuwei 無為) that the utmost authority exerts to allow the utmost simplicity and “authenticity” (the zi 自 constructions) of the people. In this paper, I suggest an understanding of wu as a philosophical framework that places Pre-Qin Daoist thought as a system that both promotes our understanding of the way the world works and offers solutions to particular problems. Wu then is simultaneously metaphysical and concrete, general, and particular. It is what allows the world, the society, and the person to flourish on their own terms.
