On the Run (instrumental)

This piece was created by entering an 8-note sequence into a Synthi AKS synthesiser made by the British synthesiser manufacturer EMS and speeding it up, with an added white noise generator creating the hi-hat sound. The band then added backwards guitar parts, created by dragging a microphone stand down the fretboard, reversing the tape, and panning left to right. There are also other Synthi and VCS 3 synthesizer parts, made to sound like a vehicle passing, giving a Doppler effect. The 8 note sequence is played at a tempo of 165 BPM, while both filter frequency and resonance are modulated. Near the end, the only guitar part is heard: a chord over the explosion of the presumed aircraft. This gradually fades, segueing into the chiming clocks introduction of the following "Time".

When The Dark Side of the Moon was performed in 1972 (before the album was released), it went under the title "The Travel Sequence" and was a more simple guitar jam, without synthesisers and other electronic instruments. A short clip of this is on the DVD Classic Albums: Pink Floyd – The Making of The Dark Side of the Moon and can be heard on all performances of Pink Floyd playing the album in that year.

'We had originally go an "On the Run," a different thing, which is on a live one if you've heard one of those bootlegs, you might have heard a different version of it than is on Dark Side of the Moon. We had a sort of guitar passage, but it wasn't very good. We'd just got this new synthesizer, a briefcase model EMS-1 [Synthi AKS], and in the lid there was a little sequencer thing. I was playing with the sequencer device attachment, and came up with this sound, which is the basic sound of it. Roger sort of heard it, came over and started playing with it, too. Then he actually put in the notes that we made...it was his sequence, that "de-di-doo-de-di-dil"- -whatever it was. He made that little sequence up, but I had got the actual original sound and I actually was the one doing the controlling on the take that we used. Then we chucked all sorts of things over the top of it afterwards.'

— David Gilmour[6]

"Everything you hear on that track, apart from the sound effects, was done live. It was all coming out of the Synthi A. Even the hi-hat over the top of it was done on that synth. There was no means of synchronising any two performances – that's why it was live. Even on the road, before a show, they would have to punch in the notes of the sequence manually, very slowly, then speed it up on playback to give the fast, sequenced effect you hear on the record.'

— Alan Parsons, engineer[7]

In a contemporary review for The Dark Side of the Moon, Loyd Grossman of Rolling Stone described "On the Run" as a "standout with footsteps racing from side to side successfully eluding any number of odd malevolent rumbles and explosions only to be killed off by the clock's ticking that leads into "Time."[8]

During the first official performance of Dark Side of the Moon, at the Rainbow Theatre on 17 February 1972, a version of this song was played with guitar, keyboard and drums instead of the synthesizer track that appeared on the album. Subsequent performances matched the album version and, at the end of the song, a model aeroplane would fly from one end of the arena to the other, appearing to crash in a brilliant explosion. The same effect was used in the A Momentary Lapse of Reason tour, but with a flying bed rather than an aeroplane. The Division Bell tour would reuse the aeroplane, only this time with the back of it in flames for additional effects.

A live version of the song can be heard on the Delicate Sound of Thunder concert video, although it did not appear on the album release, however, it appears on the 2019 reissue and remixed version of the album. Another live version appears on the CD, vinyl, and DVD releases of Pulse.

Roger Waters and his solo band performed this song live from 2006 to 2008 during his tour, The Dark Side of the Moon Live.

The song was used by longtime public address announcers Tommy Edwards and Ray Clay of the Chicago Bulls organization during the Michael Jordan era as the theme for the visiting team at Bulls home games. This also marked the first use of songs of any kind in the live setting in the NBA.

During their 1970s "Musicradio" era, Chicago radio station WLS-AM 890 used part of the song as background music for recorded prize and contest phone calls that were played on-air.
