Phase 4: Developing content for the table and the body. November 07 - October 08

This phase was principally about the vibration sensation experience.

I considered the constraints of the sensation medium and how to deliver within these. I focused on the basic elements that made up different experiences of sensation, directing my compositions to sensation without complementary or leading sound.

 

Phase 4: Overview

I developed a second composition that combined sensation and hearing, and attempted to provide more space for improvisation and gesture when making sensation. This presented new challenges around how different frequencies and intensities of low frequency signals would interact when presented as sensation.

When interacting multiple vibration tones, I experienced phase interference / cancellation issues (modulations and collapse of the vibration signal). These suggested tight limitations on building sensation composition. I developed further experiments and a working methodology from this finding. A composition made for sensation without sound helped to solidify and apply my findings.

The work also helped me to set logical boundaries when placing compositions within the spectrum between symbiotic or ‘contrapuntal’ interaction between the acoustic and tactile elements.

Overview of research outcomes

This period explored all of my principal research aims:

A main finding was that texture was integral to how vibration engages with the body, over tone, frequency or other aspects of timbre.

I also identified and began to address conceptual challenges about using vibration as a medium to express and communicate.

At the end of this phase I found a comfortable and successful range of approaches to sensation composition, based on a more developed understanding of sensation perception.
