"Mother" is a song by Pink Floyd. It appears on The Wall album, released in 1979. Composition "Mother" is 5:32 in length. The majority of the song is in G major, though the chorus is predominantly a plagal cadence in C major. The song is notable for its varied use of time signatures, such as 5/8 and 9/8. Pink Floyd drummer Nick Mason found these time-signature changes difficult to learn, and, with the band recording on a very tight schedule, ceded the drumming duties to session drummer Jeff Porcaro. The song begins quietly with solo voice and a single acoustic guitar, and gradually expands its instrumentation to include, by song's end, reed organ, piano, drums, electric bass, and electric guitar. The song has a short introduction, consisting only of a sharp inhalation and rapid exhalation before the first verses are sung by Roger Waters. The verse timing progression is: 5/8 - 8/8 × 4 - 5/8 - 8/8 × 8 - 6/8 - 8/8 × 2 - 5/8 - 8/8 × 4 - 5/8 - 8/8 × 8 - 6/8 - 8/8 × 3. The chorus, sung by David Gilmour, starts on two measures of 4/4 before going into 6/8 (or "compound duple meter") for most of the chorus, in a narrative response to the first set of lyrics. There is also one measure of 9/8. A guitar solo follows over a chord progression in 4/4 time. Waters sings another verse, which is once more followed by Gilmour's chorus (with different lyrics). Finally, the song concludes with an arrangement stripped back down to one acoustic guitar and Waters's voice, and a ritardando in which Waters sings, "Mother, did it need to be so high?", a reference to the metaphorical wall constructed by the character Pink. The song ends on the subdominant, C major, which may create an "unfinished" or "dissatisfying" feeling. Waters explained to Mojo magazine that the song is about "the idea that we can be controlled by our parents' views on things like sex. The single mother of boys, particularly, can make sex harder than it needs to be." "Most of the songs I've written have always followed the lyrics," he noted. "I've often tailored the music to fit the words, especially something like 'Money' or 'Mother'." Plot The Wall tells the story of Pink, an embittered and alienated rock star.
