The song "Qué Sería De Mí" by Joan Manuel Serrat explores the idea of how our lives would be incomplete without certain elements. It starts off by questioning what would happen if the sun didn't rise, or if the number thirteen didn't exist. These rhetorical questions highlight the importance of balance and the interconnectedness of things. The lyrics then delve into different examples such as the relationship between a dog and its adversaries, like cats and fleas, or how a flower needs manure to thrive. It also reflects on the necessity of opposites, such as a bird needing air, a hammer needing a nail, and a master needing a slave. These examples emphasize the idea that existence is dependent on complementary elements. The song also mentions the knight-errant and his battles with imaginary giants, symbolizing the quest for purpose and the need for challenges. The absence of a lady and obstacles to overcome would render the knight's existence meaningless. As the song progresses, the lyrics shift to a more personal reflection, expressing that the singer himself would be incomplete without the presence and love of another person. The metaphor of a spinning top without its string, or a mouth without someone's skin, illustrates the emptiness felt without the connection and affection of a loved one. The verses then continue to explore other examples, pondering what an angel would be without temptation, or faith without miracles. The song mentions a bicycle without wheels, a knife without a sharp edge, and a puppet without strings, highlighting how these objects lose their purpose and functionality without their essential components. The lyrics also touch upon how waves need seas, summers need siestas, and roosters need their crest and crowing. These combinations represent the natural order of things and the fulfillment that comes from having all the necessary components in place. The song concludes by contemplating the idea of clouds without skies, and bread without imagination, leaving unanswered questions about what the singer would be without the person they are addressing. It expresses the deep connection and dependence they have, emphasizing that life would be incomplete without this individual. In essence, "Qué Sería De Mí" is a reflection on the importance of interdependence, balance, and connection in our lives. It reminds us that without certain elements, both tangible and intangible, our existence would be incomplete and lacking meaning.
