Alvin Lucier - I am Sitting in a Room
I am sitting in a room (1969) is one of composer Alvin Lucier’s best known works, featuring Lucier recording himself narrating a text, and then playing the recording back into the room. […] and this process is repeated. Since all rooms have characteristic resonance frequencies, 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.
