    The goal of this project is to produce a software musical instrument using chaotic processes as a sound synthesis method. Real-time control through MIDI note messages and continuous controllers is required. Early results are described, along with suggestions for continuing work

    Dynamical Interactions with Electronic Instruments

    Get PDF
    This paper examines electronic instruments that incorporate dynamical systems, where the behaviour of the instrument depends not only upon the immediate input to the instrument, but also on the past input. Five instruments are presented as case studies: Michel Waisvisz’ Crackle-box, Dylan Menzies’ Spiro, no-input mixing desk, the author’s Feedback Joypad, and microphone-loudspeaker feedback. Links are suggested between the sonic affordances of each instrument and the dynamical mechanisms embedded in them. These affordances are contrasted with those of non-dynamical instruments such as the Theremin and sample-based instruments. This is discussed in the context of contemporary, material-oriented approaches to composition and particularly to free improvisation where elements such as unpredictability and instability are often of interest, and the process of exploration and discovery is an important part of the practice

    Of epistemic tools: musical instruments as cognitive extensions

    Get PDF
    This paper explores the differences in the design and performance of acoustic and new digital musical instruments, arguing that with the latter there is an increased encapsulation of musical theory. The point of departure is the phenomenology of musical instruments, which leads to the exploration of designed artefacts as extensions of human cognition – as scaffolding onto which we delegate parts of our cognitive processes. The paper succinctly emphasises the pronounced epistemic dimension of digital instruments when compared to acoustic instruments. Through the analysis of material epistemologies it is possible to describe the digital instrument as an epistemic tool: a designed tool with such a high degree of symbolic pertinence that it becomes a system of knowledge and thinking in its own terms. In conclusion, the paper rounds up the phenomenological and epistemological arguments, and points at issues in the design of digital musical instruments that are germane due to their strong aesthetic implications for musical culture

    Rescued Music and Music which Rescues. About Wiesław Myśliwski’s Treatise on Shelling Beans

    Get PDF
    The article focuses on the interpretation of the last novel written by Wiesław Myśliwski: Treatise on Shelling Beans (Traktat o łuskaniu fasoli). The author presents a biography of the hero – a musician and homo viator. The novel describes his life and its connections with Polish history in the 20th century. Above all, it presents reflections on the role of music in culture after World War II. In his Treatise on Shelling Beans Myśliwski performs anti-logocentric turn – music is created as a sphere of art which has a/the power of salvation: it could save a human life from destruction and could stop the destruction of rudimental senses which formed European culture

    Phase synchronization of instrumental music signals

    Signal analysis is one of the finest scientific techniques in communication theory. Some quantitative and qualitative measures describe the pattern of a music signal, vary from one to another. Same musical recital, when played by different instrumentalists, generates different types of music patterns. The reason behind various patterns is the psychoacoustic measures - Dynamics, Timber, Tonality and Rhythm, varies in each time. However, the psycho-acoustic study of the music signals does not reveal any idea about the similarity between the signals. For such cases, study of synchronization of long-term nonlinear dynamics may provide effective results. In this context, phase synchronization (PS) is one of the measures to show synchronization between two non-identical signals. In fact, it is very critical to investigate any other kind of synchronization for experimental condition, because those are completely non identical signals. Also, there exists equivalence between the phases and the distances of the diagonal line in Recurrence plot (RP) of the signals, which is quantifiable by the recurrence quantification measure tau-recurrence rate. This paper considers two nonlinear music signals based on same raga played by two eminent sitar instrumentalists as two non-identical sources. The psycho-acoustic study shows how the Dynamics, Timber, Tonality and Rhythm vary for the two music signals. Then, long term analysis in the form of phase space reconstruction is performed, which reveals the chaotic phase spaces for both the signals. From the RP of both the phase spaces, tau-recurrence rate is calculated. Finally by the correlation of normalized tau-recurrence rate of their 3D phase spaces and the PS of the two music signals has been established. The numerical results well support the analysis

    Ars Informatica -- Ars Electronica: Improving Sonification Aesthetics

    Get PDF
    In this paper we discuss æsthetic issues of sonifications. We posit that many sonifications have suffered from poor acoustic ecology which makes listening more difficult, thereby resulting in poorer data extraction and inference on the part of the listener. Lessons are drawn from the electro acoustic music community as we argue that it is not instructive to distinguish between sonifications and music/sound art. Edgar Var`ese defined music as organised sound and sonifications organise sound to reflect some aspect of the thing being sonified. Therefore, we propose that sonification designers can improve the communicative ability of their auditory displays by paying attention to the æsthetic issues that are well known to composers, orchestrators, sound designers & artists, and recording engineers

    Surfing the Waves: Live Audio Mosaicing of an Electric Bass Performance as a Corpus Browsing Interface

    Get PDF
    In this paper, the authors describe how they use an electric bass as a subtle, expressive and intuitive interface to browse the rich sample bank available to most laptop owners. This is achieved by audio mosaicing of the live bass performance audio, through corpus-based concatenative synthesis (CBCS) techniques, allowing a mapping of the multi-dimensional expressivity of the performance onto foreign audio material, thus recycling the virtuosity acquired on the electric instrument with a trivial learning curve. This design hypothesis is contextualised and assessed within the Sandbox#n series of bass+laptop meta-instruments, and the authors describe technical means of the implementation through the use of the open-source CataRT CBCS system adapted for live mosaicing. They also discuss their encouraging early results and provide a list of further explorations to be made with that rich new interface

    Electronic music and dance culture is interesting for its journeys through sound and explorations into bodily expression, but also for the numerous sites of cultural activity that have grown up with it or been inspired by its example. Here I draw on the work of theorists including Deleuze and Guattari to present a philosophical discussion of electronic music and dance culture informed by consideration of concrete events, including events I have experienced at first hand

    The coupling of action and perception in musical meaning formation

    Get PDF
    The embodied perspective on music cognition has stressed the central role of the body and body move- ments in musical meaning formation processes. In the present study, we investigate by means of a behavioral experiment how free body movements in response to music (i.e., action) can be linked to specific linguistic, metaphorical descriptions people use to describe the expressive qualities they perceive in the music (i.e., per- ception). We introduce a dimensional model based on the Effort/Shape theory of Laban in order to target musical expressivity from an embodied perspective. Also, we investigate whether a coupling between action and perception is dependent on the musical background of the participants (i.e., trained versus untrained). The results show that the physical appearance of the free body movements that participants perform in response to music are reliably linked to the linguistic descriptions of musical expressiveness in terms of the underlying quality. Moreover, this result is found to be independent of the participants’ musical background
