Live Coding, Live Notation, Live Performance

This paper/demonstration explores relationships between code, notation including representation, visualisation and performance. Performative aspects of live coding activities are increasingly being investigated as the live coding movement continues to grow and develop. Although live instrumental performance is sometimes included as an accompaniment to live coding, it is often not a fully integrated part of the performance, relying on improvisation and/or basic indicative forms of notation with varying levels of sophistication and universality. Technologies are developing which enable the use of fully explicit music notations as well as more graphic ones, allowing more fully integrated systems of code in and as performance which can also include notations of arbitrary complexity. This itself allows the full skills of instrumental musicians to be utilised and synchronised in the process. This presentation/demonstration presents work and performances already undertaken with these technologies, including technologies for body sensing and data acquisition in the translation of the movements of dancers and musicians into synchronously performable notation, integrated by live and prepared coding. The author together with clarinetist Ian Mitchell present a short live performance utilising these techniques, discuss methods for the dissemination and interpretation of live generated notations and investigate how they take advantage of instrumental musicians’ training-related neuroplasticity skills

Decomposing a composition: on the multi-layered analysis of expressive music performance

In our engagement with music, not only the physical experience of sound is important. Also the interplay between body movements, musical gestures and the cognitive processes of performers and listeners is part of our experience. Yet, this multimodal aspect is not always fully considered when analyzing music performance. In this paper, we want to establish a framework for a multi-layered analysis of music performance, building on data retrieved from quantitative and qualitative procedures and involving the perspectives of composer, performer and musicologist. The performance of a classical guitarist was analyzed in detail, using both a ‘bottom-up’ approach (audio-analysis and motion-capture) and a ‘top-down’ perspective (annotations from video-footage, perceived phrasing and the composer’s, performer’s and researcher’s perspective). These different analytical layers were compared and evaluated, which pointed out that multiple perspectives can reinforce each other in understanding musical intentions and can help detecting mismatches between qualitative and quantitative data. The analytical framework developed could be an important step in the coupling of performer’s intentions with the expressive enactment of a musical score

The Influence of Body Movements on Children’s Perception of Music with an Ambiguous Expressive Character

The theory of embodied music cognition states that the perception and cognition of music is firmly, although not exclusively, linked to action patterns associated with that music. In this regard, the focus lies mostly on how music promotes certain action tendencies (i.e., dance, entrainment, etc.). Only recently, studies have started to devote attention to the reciprocal effects that people’s body movements may exert on how people perceive certain aspects of music and sound (e.g., pitch, meter, musical preference, etc.). The present study positions itself in this line of research. The central research question is whether expressive body movements, which are systematically paired with music, can modulate children’s perception of musical expressiveness. We present a behavioral experiment in which different groups of children (7–8 years, N = 46) either repetitively performed a happy or a sad choreography in response to expressively ambiguous music or merely listened to that music. The results of our study show indeed that children’s perception of musical expressiveness is modulated in accordance with the expressive character of the dance choreography performed to the music. This finding supports theories that claim a strong connection between action and perception, although further research is needed to uncover the details of this connection
