Comfortably Numb

Placeholder Placeholderrtably Numb
"Comfortably Numb" is a song by the English rock band Pink Floyd, which first appears on the 1979 double album, The Wall. It was also released as a single in the same year with "Hey You" as the B-side. It is one of only three songs on the album for which writing credits are shared between Roger Waters and David Gilmour. The melody and most of the music was written by Gilmour while Waters contributed the lyrics and some additional notes. The song had the working title of "The Doctor". An early version of the song was included under this title on the "Immersion Box Set" of The Wall, released in 2012.

The song is one of Pink Floyd's most famous, and is renowned especially for its guitar solos. In 2004, the song was ranked number 314 on Rolling Stone magazine's list of the 500 Greatest Songs of All Time. In 2005, it was the last song ever to be performed by Waters, Gilmour, Wright, and Mason together. In 2011, the song was ranked 5th in the BBC Radio 4's listeners'Desert Island Discs choices.

History
While most songs on  The Wall were written by Waters alone, most of the music for "Comfortably Numb" was written by  David Gilmour, who originally recorded the instrumental demo during the latter stages of recording his  first solo album, hoping to find some later use for it. Gilmour later brought his demo of it to  The Wall sessions. In Gilmour's original demo, though there were no lyrics, he sang a melody not unlike the final version of the chorus. The verses, however, were in the key of E minor (a progression of E minor, D major, C major, A minor, and back to E minor again), rather than B minor, as in the final version. Also, the chord sequence for the final chorus line  "I have become comfortably numb" did not exist in Gilmour's demo. So, while the music is widely considered to be Gilmour's work, it's entirely possible that Roger Waters composed the chords for that line, as well as making the decision to change the verses from E minor to B minor.
