Pink Floyd - the thin ice, 1979

"The song, which is two minutes and 30 seconds in length, begins with the sound of an infant crying. The main body of the song is a '50s progression, with time signature in 6/8, commonly heard in doo-wop songs such as Ben E. King's "Stand by Me", progressing from C Major to A minor, then F Major to G Major, played softly on piano and synthesiser. The first half of the lyrics are sung by David Gilmour in a gentle tone, beginning with "Mama loves her baby", and a refrain of "Ooh babe, ooh, baby blue". A bass guitar creates a dissonant effect mid-song, when it plays an F♯ against an A minor, the major sixth of the chord, and the augmented fourth of the key. Then Roger Waters takes over the lead vocal. The piano becomes staccato, as the lyric takes on a warning tone, with Waters singing "If you should go skating/On the thin ice of modern life...."
