ALVIN LUCIER "I AM SITTING IN A ROOM"

Ignore the visuals, this is the original recording, which has such a beautiful sonic quality.
If you have a chance today, listen to the whole piece and just write your response. It can be
50-100 words.
The piece features Lucier recording himself narrating a text, and then playing the
tape recording back into the room, re-recording it. The new recording is then played back and re-recorded, and this process is repeated. Since all rooms have characteristic
resonance or
formant frequencies (e.g. different between a large hall and a small room), the effect is that certain
frequencies are emphasized as they resonate in the room, until eventually the words become unintelligible, replaced by the pure resonant harmonies and tones of the room itself.

Lucier was originally inspired to create
I am sitting in a room after a colleague mentioned attending a lecture at
MIT in which
Amar Bose described how he tested characteristics of the loudspeakers he was developing by feeding back audio into them that they had produced in the first place and then was picked up via microphones.
