Performed with The Sphere, a 4" metal bulb attached to a short tether with a pressure sensor encased inside. As the Sphere is swung around, the sensor and electronics capture physical motion and transfer them in real time to a computer with custom software. The software does an analysis of the performers gestures and maps the motions to sound performance and sonic manipulation software/hardware. This work is performed with an electronic interface device (instrument) which operates similar to a Bullroarer. The Bullroarer is an ancient Aboriginal instrument/toy that is built by attaching an 8" to 15 " rhombus shaped piece of wood to a long piece of twine or animal sinew. When the Bullroarer is swung at arms length around the user's head, an eerie whirring sound can be heard. The pitch and amplitude of the sound is dependent on the speed and force of the swing. My intention is to reference the physical action of playing and manipulating sounds with a Bullroarer by building a custom motion capture device and composing an audio performance using actions captured with this device. My device will be a spherical metal bulb approximately 4" in diameter fastened on the end of a long wire or light chain. Encased inside of the sphere is a small flat Force Sensing Resister with a small weight attached to it. When the sphere is swung around, the small weight will, under the influence of centrifugal force press against the FSR. The FSR will continuously measure the pressure and transfer that measurement to the computer running custom software which will construct the arrangement of sounds performed. Divination by Oscillation Divining is an Alchemical art that in its generally known form is concerned more closely with the knowledge of hidden things. Finding of lost things, determining the truth of a matter, location of a water source, etc. By looking into someones future, the diviner or medium can assess the particular situation and in the form of rituals evoke positive forces which can result in a positive change in the situation. An instrument of sorts is usually used to visually and symbolically assist in the focusing of energies towards achieving the goal. To divine in its truer and deeper sense is to discover by inspiration and intuition, and to stimulate imagination within and out. This is the leaping off point of reference that brings my 'instrument' into play.
