    Designing musical expression
    (Edições Universitárias Lusófonas, 2017) Sá, Adriana; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
    The term New Interface for Musical Expression (NIME) has been applied to a great variety of instruments and systems, since the first NIME conference in 2001. But what is musical expression, and how does an interface intended for idiosyncratic expression differ from ubiquitous interfaces? This paper formulates an understanding where the reciprocal interaction between performer and instrument is important. Drawing from research in perception science , interface design and music, the paper specifies methods that can be used to analyse interaction, attention dynamics and semantics. The methods are applicable to any technical platform and aesthetic approach, facilitating the discussion of creative strategies and the analysis of music experience. The paper uses these methods to describe a NIME that combines an acoustic string instrument and software that operates based on the acoustic sound. The software applies the difference between the detected pitch and the closest tone / half tone to the processing of pre-recorded sounds. The proposed methods help to explain how this NIME enables versatile musical forms, and prevents undesired outcomes. Keywords: NIME, Musical expression, Musical Interface, Perception, Attention, Semantics of Sound

    INTER-FACE: International Conference on Live Interfaces 2014
    (Universidade do Porto, CECL & CESEM (Universidade NOVA , MITPL (University of Sussex), 2015) Sá, Adriana; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
    INTER-FACE, the second International Conference on Live Interfaces, was dedicated to problematizing convergences and divergences between different understandings of performance technology. It sought to expose a variety of motivations and approaches, and discuss how specifc understandings of ‘liveness’, ‘immediacy’, ‘timing’ or ‘fow’ manifest in performance with digital media. INTER-FACE gathered paper presentations, performances, interactive installations, poster demonstrations and workshops. It happened in Lisbon, Portugal, at the Fine Arts Faculty of the University Lisbon (FBAUL); the School of Music of the National Conservatorium (EMCN); ZDB; the National Museum for Contemporary Arts (MNAC) and the Institute of Art, Design and Enterprise (IADE). The Conference is biannual, and these Proceedings are published a year after the conference itself. The authors had the opportunity to strengthen their work after the presentation at the conference, beneftting from the feedback of the other participants and the editorial peer-review. Keywords: Live interfaces, Performance, Art installation, instrument design, NIME

    Repurposing video game software for musical expression: a perceptual approach
    (Edições Universitárias Lusófonas, 2014) Sá, Adriana; CICANT (FCT) - Centro de Investigação em Comunicação Aplicada, Cultura e Novas Tecnologias
    The article exposes a perceptual approach to instrument design and composition, and introduces an instrument that combines acoustic sound, digital sound, and digital image. We explore disparities between human perception and digital analysis as creative material. Because the instrument repurposes software intended to create video games, we establish a distinction between the notion of “flow” in music and gaming, questioning how it may substantiate in interaction design. Furthermore, we describe how the projected image creates a reactive stage scene without deviating attention from the music. Keywords: Perception, flow, musical expression, audio-visual mapping
