Environmental sound sculpture devised in 1973 by the American pianist and composer David Tudor. It was based on the concept of the ‘instrumental loudspeaker’, which Tudor developed in 1966 and used in all four works in the Rainforest series, starting in 1968. The first instrumental loudspeakers consisted of containers into one end of which electronic or other sounds were fed through small loudspeakers. The sounds were picked up by microphones at the other end and passed to a conventional sound system. The containers in these early examples were metal boxes into which various materials were introduced to filter the signals acoustically as they passed between loudspeaker and microphone. In Rainforest IV the boxes are replaced by a great variety of objects, many of them in everyday use or scrap materials, to which loudspeaker-like transducers are attached; together these create an elaborate sound environment, which is operated by members of the group Composers Inside Electronics (founded by Tudor)....

For a long while successive periods in the history of the gramophone (or phonograph) tended to follow one another at approximately 25-year intervals. The invention itself dates from 1877, the year in which the Frenchman Charles Cros (1842–88) deposited with the Académie des Sciences a paper containing proposals for the reproduction of sound, without putting his theories to a practical test, and in which an American, Thomas Edison (1847–1931), independently began to study sound recording and reproduction as part of his wider researches into telegraphy, and was soon able to recite Mary had a Little Lamb into a crude recording horn and to hear his words immediately and recognizably played back.
Thereafter, nothing very momentous happened until the last decade of the century. The early death of Cros and Edison’s lack of interest in the musical possibilities of his invention left the field open for a while to the apparently extensive and important but somewhat shadowy achievements of an Italian cavalry officer, Lt Gianni Bettini, who indulged in activities of considerable scope and value, and actually recorded the voice of Pope Leo XIII in his 93rd year. With the exception of an undoubtedly genuine recording of the great Polish soprano, Marcella Sembrich, which was romantically discovered in the attic of a New Zealand hotel, scrupulously dubbed and made generally available in ...
