=== Instrumentation ===
The album features metronomic sound effects during "Speak to Me" and tape loops for the opening of "Money". Mason created a rough version of "Speak to Me" at his home before completing it in the studio. The track serves as an [[overture]] and contains cross-fades of elements from other pieces on the album. A piano chord, replayed backwards, serves to augment the build-up of effects, which are immediately followed by the opening of "Breathe". Mason received a rare solo composing credit for "Speak to Me".{{refn|Mason is responsible for most of the sound effects used on Pink Floyd's discography.|group="nb"}}<ref name="Schaffnerp164" /><ref>{{Harvnb|Mason|2005|p=172}}</ref>

The sound effects on "Money" were created by splicing together Waters' recordings of clinking coins, tearing paper, a ringing cash register, and a clicking adding machine, which were used to create a 7-[[beat (music)|beat]] effects loop. This was later adapted to four tracks to create a "walk around the room" effect in quadraphonic presentations of the album.<ref>{{Harvnb|Harris|2006|pp=104–105}}</ref> At times, the degree of sonic experimentation on the album required the studio engineers and all four band members to operate the mixing console's faders simultaneously, in order to mix down the intricately assembled multitrack recordings of several of the songs, particularly "On the Run".<ref name="makingof" />

Along with conventional rock band instrumentation, Pink Floyd introduced prominent synthesisers to their sound. The band experimented with an [[EMS VCS 3]] on "Brain Damage" and "Any Colour You Like", and a [[Synthi A]] on "Time" and "On the Run".<!--VCS 3 and Synthi A are technically the same, only using different housings--> They also devised and recorded unconventional sounds, such as assistant engineer Peter James<ref name="Alan Parsons"/> running around the studio's echo chamber during "On the Run",<ref>{{Harvnb|Harris|2006|pp=118–120}}</ref> and a specially treated [[bass drum]] made to simulate a human [[Heart rate|heartbeat]] during "Speak to Me", "On the Run", "Time" and "Eclipse". This heartbeat is most prominent in the intro and the outro to the album, but it can also be heard sporadically on "Time" and "On the Run".<ref name="makingof" /> "Time" features assorted clocks ticking, then chiming simultaneously at the start of the song, accompanied by a series of [[Rototom]]s. The recordings were initially created as a quadraphonic test by Parsons, who recorded each timepiece at an antique clock shop.<ref name="Schaffnerp164">{{Harvnb|Schaffner|1991|p=164}}</ref> Although these recordings had not been created specifically for the album, elements of this material were eventually used in the track.<ref>{{Harvnb|Mason|2005|p=173}}</ref>
