"Smoke on the Water" is a song by the British rock band Deep Purple. It was first released on their 1972 album Machine Head. In 2004, the song was ranked number 434 on Rolling Stonemagazine's list of the 500 greatest songs of all time, ranked number 4 in Total Guitar magazine's Greatest Guitar Riffs Ever, and in March 2005, Q magazine placed "Smoke on the Water" at number 12 in its list of the 100 greatest guitar tracks.
"Smoke on the Water" is known for and recognizable by its central theme, a four-note "blues scale"(G minor blues scale) melody harmonised in parallel fourths. The riff, played on a Fender Stratocaster electric guitar by Ritchie Blackmore, is later joined by hi-hat and distorted organ, thendrums, then electric bass parts before the start of Ian Gillan's vocal.
We all came out to Montreux, on the Lake Geneva shorelineto make records with a mobile, we didn't have much time—Opening lyrics
Jon Lord doubles the guitar part on a Hammond C3 organ played through a distorted Marshall amp, creating a tone very similar to that of the guitar. Blackmore uses either a plectrum upstroke (to accentuate the tonic) or a double finger pluck.
The song order is intro(riff)-verse-chorus-riff-verse-chorus-riff-guitar solo-riff-verse-chorus-riff-organ solo. The first solo is performed on guitar by Ritchie Blackmore, and the second and final solo is performed on an organ by Jon Lord until the song fades out.
The lyrics of the song tell a true story: on 4 December 1971 Deep Purple had set up camp in Montreux, Switzerland to record an album using a mobile recording studio (rented from the Rolling Stones and known as the Rolling Stones Mobile Studio—referred to as the "Rolling truck Stones thing" and "the mobile" in the song lyrics) at the entertainment complex that was part of the Montreux Casino (referred to as "the gambling house" in the song lyric). On the eve of the recording session a Frank Zappa and The Mothers of Invention concert was held in the casino's theatre. In the middle of Don Preston's synthesizer solo on "King Kong", the place suddenly caught fire when somebody in the audience fired a flare gun into the rattan covered ceiling, as mentioned in the "some stupid with a flare gun" line. The resulting fire destroyed the entire casino complex, along with all the Mothers' equipment. The "smoke on the water" that became the title of the song (credited to bass guitarist Roger Glover, who related how the title occurred to him when he suddenly woke from a dream a few days later) referred to the smoke from the fire spreading over Lake Geneva from the burning casino as the members of Deep Purple watched the fire from their hotel. The "Funky Claude" running in and out is referring to Claude Nobs, the director of the Montreux Jazz Festival who helped some of the audience escape the fire.
Left with an expensive mobile recording unit and no place to record, the band was forced to scout the town for another place to set up. One promising venue (found by Nobs) was a local theatre called The Pavilion, but soon after the band had loaded in and started working/recording, the nearby neighbours took offence at the noise, and the band was only able to lay down backing tracks for one song (based on Blackmore's riff and temporarily named Title n°1), before the local police shut them down.
Finally, after about a week of searching, the band rented the nearly-empty Montreux Grand Hotel and converted its hallways and stairwells into a makeshift recording studio, where they laid down most of the tracks for what would become their most commercially successful album, Machine Head.
The only song from Machine Head not recorded entirely in the Grand Hotel was "Smoke on the Water" itself, which had been partly recorded during the abortive Pavilion session. The lyrics of "Smoke on the Water" were composed later, and the vocals were recorded in the Grand Hotel.
On the Classic Albums series episode about Machine Head, Ritchie Blackmore claimed that friends of the band were not a fan of the classic Smoke on the Water riff, because they thought it was too simplistic. Blackmore retaliated by making comparisons to Beethoven's 5th Symphony's First Movement, which revolves around a similar four note arrangement—and is arguably the most famous piece of music in the world.
