Emergent Story Generation: Lessons from Improvisational Theater

An emergent approach to story generation by computer is characterized by a lack of predetermined plot and a focus on character interaction forming the material for stories. A potential problem is that no interesting story emerges. However, improvisational theater shows that – at least for human actors – a predetermined plot is not necessary for creating a compelling story. There are some principles that make a successful piece of improvisational theater more than a random interaction, and these principles may inform the type of computational processes that an emergent narrative architecture draws from. We therefore discuss some of these principles, and show how these are explicitly or implicitly used in story generation and interactive storytelling research. Finally we draw lessons from these principles and ask attention for two techniques that have been little investigated: believably incorporating directives, and late commitment

Echo's body: play and representation in interactive music software

This paper examines Hans Georg Gadamer's theory of play (as it is presented in Truth and Method) and adapts it to the context of interactive music software. I aim to show that interactive technological environments afford play in ways which, because they relate to truth and selfhood, are cognitively and philosophically significant and are not 'merely' playful

Opening opera: developing a framework that allows for the interactive creative processes of improvised theatre in the productions of new music-dramas

Opening Opera explores creative collaboration and dramatic improvisation in new music-dramas. Looking towards the art of improvised theatre, the aim is to achieve a dramatic process in opera which facilitates a flexible kind of dramaturgy, enabling singers and directors to lead and inform certain creative processes that are normally in the hands of the operatic composer and/or librettist alone. By developing particular unorthodox scoring methods, along with specific rehearsal schedule considerations that support these flexible processes, the composer attempts to create not improvised opera, but what could be called an open opera, where the compositional focus is working with a free vocal line with active accompaniment. This framework is one in which the composer provides the parameters and material for dramatic and compositional flexibility, and then ‘takes a step back’ during a collaborative and improvisational process, whilst retaining sufficient leadership and creative authority to realise the overarching structure satisfactorily. In order to develop said unorthodox scoring methods and processes, the creative team explored and informed structural, dramatic, technical and musical aspects of new material, utilising the performers’ specialised training and experience in an interactive creative process. This exploration brought up questions such as: how to allow an open process such as this one while still attempting to retain overarching artistic control; what are the parameters that the composer will need to determine (i.e. keep 'closed'); and what are the parameters that he must allow to be spontaneous, improvised or open? By opening up the process in this way, interesting genre specific problems were exposed that are more often than not left implicit rather than explicit by creators of opera. This exploration reveals knowledge beneficial to tutors, composers, librettists, singers, conductors and directors of music-dramas. This inquiry is primarily grounded in several methods extracted and modified from improvised theatre, opera, and open-scored compositions of the mid-20th century. The musical and qualitative data discussed in this commentary emerged during the preparation, writing and production of the author’s original music-drama studies. Studies include excerpts from two chamber operas; A Glacier’s Requiem (2013) (or “Bráð” in the original Icelandic), and Évariste (2014); a short monodrama study, Solitude 1 (2015); and a chamber opera presented in its entirety, After the Fall (2017)

Seeking out the spaces between: Using improvisation for collaborative composition and interactive technology

Copyright © 2010 ISASTThis article presents findings from experiments into piano performance live electronics undertaken by the author since early 2007. The use of improvisation has infused every step of the process---both as a methodology to obtain meaningful results using interactive technology and as a way to generate and characterize a collaborative musical space with composers. The technology used has included pre-built MIDI interfaces such as the PianoBar, actuators such as miniature DC motors and sensor interfaces including iCube and the Wii controller. Collaborators have included researchers at the Centre for Digital Music (QMUL), Richard Barrett, Pierre Alexandre Tremblay and Atau Tanaka. In seeking to create responsive “performance environments” at the piano, I explore live, performative control of electronics to create better connections for both performer (providing the same level of interpretive freedom as with a “pure” instrumental performance) and audience (communicating clearly to them). I have been lucky to witness first-hand many live interactive performances and to work with various empathetic composers/performers in flexible working environments. Collaborating with experienced technologists and musicians, I have witnessed time and again what, for me, is a fundamental truth in interactive instrumental performance: As a living, spontaneous form it must be nurtured and informed by the performer’s physicality and imagination as much as by the creativity or knowledge of the composer and/or technologist. Specifically in the case of sensors, their dependence on the detail of each person’s body and reactions is so refined as to necessitate, I would argue, an entirely collaborative approach and therefore one that involves at least directed improvisation and, more likely, fairly extensive improvised exploration. The fundamentally personal and intimate nature of sensor readings---the amount of tension created by each performer, the shape of the ancillary gestures or the level of emotional involvement (especially relevant when using galvanic skin response or EEG)---makes creating pieces with sensors extremely difficult for a composer to do in isolation. Improvisation therefore provides a way for performer and composer to generate a common musical and gestural language. Related to these issues is the fact that the technical or notational parameters in interactive music are not yet (and may never be) standardized, thereby creating a very real and practical need for improvisation to figure at least somewhere in the process.This study is funded by the Arts and Humanities Research Council

Novel Methods in Facilitating Audience and Performer Interaction Using the Mood Conductor Framework

While listeners’ emotional response to music is the subject of numerous studies, less attention is paid to the dynamic emotion variations due to the interaction between artists and audiences in live improvised music performances. By opening a direct communication channel from audience members to performers, the Mood Conductor system provides an experimental framework to study this phenomenon. Mood Conductor facilitates interactive performances and thus also has an inherent entertainment value. The framework allows audience members to send emotional directions using their mobile devices in order to “conduct” improvised performances. Emotion coordinates indicted by the audience in the arousal-valence space are aggregated and clustered to create a video projection. This is used by the musicians as guidance, and provides visual feedback to the audience. Three different systems were developed and tested within our framework so far. These systems were trialled in several public performances with different ensembles. Qualitative and quantitative evaluations demonstrated that musicians and audiences were highly engaged with the system, and raised new insights enabling future improvements of the framework
