Money is a song from British progressive rock band Pink Floyd's 1973 album, The Dark Side of the Moon. It is the only song on the album to hit the top 20 in the United States charts. On the original LP, it opened the second side of the album. It was written by Roger Waters. The guitar solo is ranked number 62 on Guitar World's "100 Greatest Guitar Solos".
"Money" is notable for its introductory passage of cash registers dinging and coins clinking, much like "Time". However, unlike "Time", the 'money' sounds were recorded specifically for the album, and are featured in a 7/4 beat rhythm.
"Money", a riff-driven song, is notable for the unusual 7 beat time signature. The song is also notable for its dramatic change to 4/4 time for an extended guitar solo, after which the song returns to 7/8, then ends in 4/4. Pink Floyd guitarist David Gilmour suggested the change in time signature was likely introduced to make things a little easier for him.
