"Time" is a song by the English progressive rock band Pink Floyd. It is included as the fourth track on their eighth album The Dark Side of the Moon (1973) and was released as a single in the United States. Bassist Roger Waters wrote the lyrics. Keyboardist Richard Wright shares lead vocals (his last until "Wearing the Inside Out" on The Division Bell) alongside guitarist David Gilmour. The lyrics deal with the passage of time. Waters got the idea when he realised he was no longer preparing for anything in life, but was right in the middle of it. He has described this realisation taking place at ages 28 and 29 in various interviews. It is noted for its long introductory passage of clocks chiming and alarms ringing. The sounds were recorded in an antique store made as a quadrophonic test by engineer Alan Parsons, not specifically for the album. The album track also includes a reprise of the song "Breathe". It is the only song on the album to credit all four principal members for songwriting, and the last to do so in the band's discography. Composition "Time" is in the key of F♯ minor. Each clock at the beginning of the song was recorded separately in an antiques store. These clock sounds are followed by a two-minute passage dominated by Nick Mason's drum solo, with rototoms and backgrounded by a tick-tock sound created by Roger Waters picking two muted strings on his bass. With David Gilmour singing lead on the verses and with Richard Wright singing lead on the bridges and with female singers and Gilmour providing backup vocals, the song's lyrics deal with Roger Waters' realization that life was not about preparing yourself for what happens next, but about grabbing control of your own destiny. According to an interview by Phil Taylor in 1994, David Gilmour had been using a Lexicon PCM-70 to store the circular delay sounds heard in "Time", which could duplicate the kind of echo he used to get from his old Binson echo unit. The verse chords cycle through F♯ minor, A major, E major, and F♯ minor again. During this section, Gilmour's guitar and Wright's keyboards are panned to the extreme right and left of the stereo spectrum, respectively. Gilmour sings lead during this section. The bridge section, with Wright singing lead, has a notably "thicker" texture, with the female backing vocalists
