It plays arpeggios over E and D minor added ninth chords . The alternate stringing allows for adjacent pitches (such as the E, F ♯, and G of the Em9 chord) to ring out separately on separate strings throughout the arpeggio . A fretless bass enters, also played by guitarist David Gilmour rather than usual bassist Roger Waters . Next to join in is the Fender Rhodes electric piano by Rick Wright, Gilmour's vocals, and overdubbed acoustic guitar and drums at the start of the second verse . In the middle is a guitar solo which is played over the album's leitmotif of the melody to "Another Brick in the Wall" (in E minor and A minor, rather than D minor). After the solo, Roger Waters sings the lead vocal for the rest of the song . The bridge is a chord sequence later heard on the album as "Bring the Boys Back Home", ending on an E minor chord, leading to a reprise of the instrumental introduction, augmented by prominent ARP Quadra riffs and a faintly audible sound of a drill . At this point, there is a piece of indecipherable whispering from the left channel . Drums and vocals then join in . At about 3: 23 into the song, a sonar - like sound, similar to the ping in "Echoes", is heard . When Waters sings the final verse, he does so one octave higher than Gilmour, with the highest note being the first C above middle C . </P> <P> The Wall tells the story of Pink, an alienated young rock star who is retreating from society and isolating himself . In "Hey You", Pink realizes the mistake he made in shunning society, and attempts to regain contact with the outside world . However, he cannot see or hear beyond the wall . Pink's call becomes more and more desperate as he begins to realize there is no escape . </P> <Table> <Tr> <Td> </Td> <Td> This section does not cite any sources .
