In Henry Miller's "Tropic of Cancer," the author illustrates that the act of singing is fundamentally simple yet profound. He emphasizes that anyone can sing as long as they are willing to express themselves. The process requires basic physical elements, like vocal cords and breath, along with a minimal understanding of music, but it does not rely on having instruments or a specific skill set. The core aspect is the desire to sing and communicate through that medium.

Miller's reflections highlight the importance of self-expression and the joy that comes from it. He conveys that singing is not just about technique; it's about the inner motivation to share one’s voice. By affirming that he is singing, he embraces the notion of creation and the personal significance it holds. Ultimately, the message resonates with the idea that true expression is universal and accessible to anyone willing to engage in it.
