I am sitting in a room
"I am sitting in a room different from the one you are in now. I am recording the sound of my speaking voice and I am going to play it back into the room again and again until the resonant frequencies of the room reinforce themselves so that any semblance of my speech, with perhaps the exception of rhythm, is destroyed. What you will hear, then, are the natural resonant frequencies of the room articulated by speech. I regard this activity not so much as a demonstration of a physical fact, but, more as a way to smooth out any irregularities my speech might have."
- 1969
- Lucier recording himself narrating a text, and then playing the recording back into the room, re-recording it, and then repeated
- Certain frequencies are emphasized, until the words become unrecognisable, replaced by the harmonies and tones of the room itself.
