The title track is a thirty-minute piece originally intended as a background
drone for guitarist
Robert Fripp to play over in a series of concerts. Eno set up a
synthesizer with built-in memory along with a
tape delay system, but was immediately interrupted: "people started knocking on the door, and I was answering the phone and adjusting all this stuff as it ran. I almost made that without listening to it. It was really automatic music." It begins with two melodic phrases of different lengths played back from a
synthesizer's
digital recall system. The equipment used in this case was an
EMS Synthi AKS, which had a then-exotic, built-in digital sequencer. This signal is then run through a
graphic equaliser to occasionally change its timbre. Eno described the music as the result of a self-generating, self-regulating system, with the input to the system taking the form of two- or four-measure fragments of Pachelbel's canon, and the system being the performers with a set of instructions. Each variation involves a different way of manipulating and overlaying the musical fragments. In the first piece, "Fullness of Wind", the players' tempos are decreased, with the rate of decrease being related to the relative pitch of the instruments, so that lower instruments are slowest. In the second piece, "French Catalogues", groups of notes are associated with time-related directions from different parts of the score. The third piece, "Brutal Ardour", presents the players with sequences of notes that are related but of different lengths. The titles of these pieces were derived from inaccurate French-to-English translations of the liner notes of a version of Pachelbel's Canon performed by the orchestra of
Jean-François Paillard.
Discreet Music was the third (of four) simultaneous releases on Eno's new
Obscure Records label. It was re-released on the
Virgin label in 2004. On CD reissues, a full minute of silence separates the two halves. ==Reception and legacy==
