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.
