Event overview
Adriana Sa performs the finale of her PhD with an instrument which combines a zither and 3D software that operates on amplitude and pitch detection from the zither input.
Adriana will perform with an audio-visual instrument which combines a zither (acoustic multi-string instrument with fretboard) and 3D software that operates based on amplitude and pitch detection from the zither input.
The difference between the detected pitch from the zither and the closest tone/ half tone is applied to the processing of digital sound and image, as well as the audio-visual mapping. The instrument was developed along with a perceptual approach to audio-visual instrument design, composition and performance. The approach informs practical work as well as a parametric visualisation model, which can be used to analyse sensory dominance, sonic expression and spatial presence in any audio-visual performance language.
The interaction with my instrument conveys complex sonic constructions. The image extends the physical performance space to a digital 3D world beyond the screen. It functions as a stage scene, which reacts to the sound without distracting attention from the relation between the sounds themselves. This is challenging, because usually vision dominates over audition. To clarify the problem, I extrapolated from audio-visual theory, psychology, neuroscience, interaction design and musicology.
The investigations led to three creative principles which inform the design of my instrument:
a) to threshold the performer’s control over the instrument and the instrument’s unpredictability, in ways that convey musical expression
b) to facilitate perceptual simplification of visual dynamics
c) to create an audio-visual relationship that produces a sense of causation, and simultaneously confounds the cause and effect relationships.
The parametric visualisation model can reveal how any audio-visual performance work might converge or diverge from these creative principles. It combines parameters for interaction, sonic & visual dynamics, audio-visual relationship, physical performance setup and semantics.
