“Singing candles” (Zingende kaarsen) – part of 'Inner Lives of a Sleeper'
Version with multiple candles/speakers
The movement (flickering) of a candle light is detected by a light sensor. This signal is amplified and fed to a hanging loudspeaker closeby the candle. The sound (air movement) in it's turn influences the flame, creating a unpredictable feedback system. Small influences from the environment (people moving, breathing...) trigger the resonance to start or stop.
Three or more installations of different size of speakers – means different sounds, are set-up in one space and creating together a kind of orchester.
2.SPACE & LIGHT
The room should be silent and completely dark.
Preferably a blackbox is made with black tissue, and the floor is covered by a carpet.
Minimal surface: 6x6 m² – ideally 8x8 m².
Height: preferably more than 4 m.
The installation is positioned around the middle and needs at least 3 hanging points (eg. 3 pipes) for the speakers and the sensors. (see drawing)
The spectator is invited to either stand or sit on the pillows on the floor – playing with the candle or just listening to the concert of the loudspeakers.
At the entrance a passage lock should allow the spectators to enter & leave the room so that the outside light doesn't hit the sensor.
An artificial light would create an ugly 50Hz buzz through the speaker. It is possible to light the (entrance of the) space with light on DC (eg. batteries or power supply).
Ouside the visitors may fill out an enquête around the sleep/breath, on paper or possibly online, at a table – as well having some books to read or just sit there on chairs or pillows.
What we need:
2 professional amplifiers (low frequencies!) min. 250 W stereo (we can provide 1)
1 mixing console (4 in 4 out) with good microphone preamps with phantom power (we can provide this)
Wood or construction pipes and black tissue (molton) to make the blackbox and entrance
3 (or more) diagonal pipes or other solution for hanging the speakers and sensors (some kg)
A dark carpet to cover the whole floor.
10 to 20 cushions (light color) to sit on
Dimmed light and passage lock for entrance
Fire extinguishers (how many?)
1 person to check and replace the candle when necessary - visitors could blow out the candle
A table and some chairs for the survey
What we bring:
1 professional amplifier (low frequencies!)
3 (or 4) loudspeakers, hanging on two electric wires
3 (or 4) candlelights on a base
3 (or 4) light sensors with XLR exension cords
