Black Lava



The experiment
Explore cymatics using fine powders, creating small clouds and eruptions.

The object
A small dish of black pigment is placed directly on a cut back speaker cone. The device is placed under a glass cloche to contain the dust particulate. As the vibrations get larger the pigment begins to billow making larger clouds inside the jars. After the sound the specimen jar looks like a speaker valve. Perhaps there area number of objects with different coloured pigments....

Sound
Using the process voice pitch shifted, small eruptions can be made. Using bass oscillator notes clouds and bills can be made.
(Perhaps a performance element for Sonya, or a crescendo for trio performance).

Audience experience
Unmediated... Audience need to be able to see the jars - perhaps spread out across the tables...

Use
Performance (voice and tone generator)

Equipment
6? cut back speakers
3 amps
6 dishes
pigments
6 cloches

Kaleidophone Lissajous Generator

The experiment Explore and expand on the design of Charles Wheatstones Kaleidophone (1827) and Jules Lissajous's  Tuning Fork mirror technique (1857) to create Lissajous figures that draw the sound from purely mechanical means, essentially 'drawing' the sound. The object Two rods attached to cut down speakers with objects placed perpendicular to each other. A small laser is projected onto one mirror, reflected off the second mirror onto a screen creating a Lissajous figure that responds to the sound being played through the speaker. Sound Pure tones, mixed with noise to illustrate the different patters. Pre-recorded. Perhaps voice responsive - voices fed to each speaker (more experiments needed) Audience experience Viewed on small screen Use Installation & performance Equipment 2 cut down speakers, rods with small mirrors. Secured so they don't move with vibration. 1 x stereo Amplifier (Idea that there may be 3 speakers one for each voice - to ...

Acoustic Inertia

The experiment A bowl is placed over an oval speaker cone. The vibration of the cone causes the bowl to rock back and forth. When using ball bearings, the balls move around in the bowl adding rattling tones to the sound. When using a liquid, the vibrations make cymatic patterns in the liquid, but also inertia means that the liquid appears to stay in the same place while the bowl moves around it. The object Perhaps four speakers are arranged, two with ball bearings, two with liquid. They can be arranged in a number of patterns or configurations. Sound Responds to low frequency bass sounds - can provide bass lines in overall installation soundscape. Pre-recorded. Audience experience Unmediated Use Installation and performance bass lines Equipment 4 x speakers with oval cones 2 x stereo amps 4 x metal bowls matching the speaker cone size ball bearings rheoschopic liquid Also viewable on Vimeo:  https://vimeo.com/337667196
