The music lyrics noted multiple times in Anthony Burgess' novel A Clockwork Orange are
And I will go back to my darling, my darling,
When you my darling are gone.
These lyrics express the idea of moving back and forth in time and an exploration of both good and evil. The lyrics, therefore, speak to the fact that one floats back and forth between the forces and pressures associated with good and bad behaviors.
Another lyric which is brought up shows the violent and aggressive attitudes of the characters in the novel.
Boy, thou uproarious shark of heaven,
Slaughter of Elysium,
Hearts on fire, aroused, enraptured,
We will tolchock you on the rot and kick
Your grabzny vonny bum.
These lyrics certainly speak to the violent and aggressive attitudes of the characters. The words evoke feelings of hatred (for the characters) and fears (for the readers and those the violence is enacted upon).
Therefore, the music depicted in the novel symbolize the inner feelings of the characters.
