In "Songbook," Nick Hornby reflects on the dual nature of musical chords. He describes them as basic elements that can be used to create simplistic songs, yet also appreciates their inherent beauty and mystery. This duality highlights how something so simple can evoke profound emotions and artistic expression.

Hornby emphasizes that even those who may be considered lacking in education or refinement can harness the power of chords to produce something impactful. This idea speaks to the universal accessibility of music, suggesting that anyone can tap into their emotional depth and creativity to create works that resonate with others.
