Its name refers to the fact that its performance requires a typewriter, while using three basic typewriter sounds: the sound of typing, the "ring" of the carriage return indicating an approaching end-of-line (a standard desk bell is used for it), and the sound of the typewriter’s carriage returning. In some cases the sound of the typewriter’s carriage returning is made by a musical gourd,[4] flute, string or other instrument.
The typewriter was modified so that only two keys work to prevent the keys from jamming. According to the composer himself, as well as other musicians, the typewriter part is difficult because of how fast the typing speed is: even professional stenographers cannot do it, and only professional drummers have the necessary wrist flexibility.[5]
It has been called one of "the wittiest and most clever pieces in the orchestral repertoire".[6] Author Steve Metcalf has written that "Despite the almost total disappearance of typewriters in everyday life, the statistics show that "The Typewriter" is still a favorite Anderson item."[7]
The typewriter is considered a percussion instrument,[8] and the typewriter part is usually performed by a percussionist or drummer, or rarely by the conductor.[9][5]
