The song "Toca Madera" by Joan Manuel Serrat is a playful and ironic take on superstitious beliefs and the human desire for luck and protection. The lyrics highlight various superstitions and precautions people take to avoid bad luck and unfortunate circumstances. The phrase "Toca Madera" translates to "touch wood," which is a common gesture believed to bring good luck and ward off misfortune. The song encourages listeners to cross their fingers, touch wood, and take various actions to avoid common superstitions, such as not walking under a ladder, avoiding the number thirteen, or encountering a black cat. Serrat sings about the belief in the power of amulets or lucky charms, such as a rabbit's foot if a mirror breaks or salt spills. He also mentions checking horoscopes and biorhythms as a way to seek guidance and avoid unfavorable events. These references reflect a reliance on external forces and rituals to bring luck and protection. However, the song also satirizes these beliefs by pointing out their absurdity. Serrat suggests that, despite all these precautions, life can still present challenges and unexpected difficulties. He humorously suggests that stepping on dog excrement brings good luck, highlighting the unpredictable nature of fate and the futility of relying solely on superstitions. Overall, "Toca Madera" serves as a lighthearted commentary on human tendencies to seek reassurance and protection through superstitious practices. It reminds listeners that while certain precautions may bring comfort, they don't guarantee a trouble-free life. The song encourages a balanced perspective, urging listeners to take a deep breath, face challenges head-on, and navigate life's ups and downs with a positive attitude.
