The song "Pendulum" by Harry Hudson explores a complicated and turbulent relationship. The lyrics describe emotions and experiences that symbolize the highs and lows of love. The line "Like raindrops when the sun shines" suggests that even in the presence of happiness, there can still be moments of sadness. Similarly, the line "Like a low life with a good high" portrays the contrast between feeling down and having moments of joy. The phrase "When the fireplace don't work right, we lost our spark on a cold night" signifies the loss of passion and connection in the relationship. It implies that their love has dwindled, possibly due to miscommunication or unresolved issues. The lyrics also touch upon the theme of sacrifice in love. "Fell in love at my own expense" suggests that the speaker invested deeply in the relationship but received little in return. The line "You say my love can't pay your rent" implies that the other person may have been more focused on materialistic gains rather than genuine love. The lyrics further express the speaker's frustration and resentment towards the other person. The line "Used to want your love, now you make me sick" illustrates a shift in emotions, where the initial desire for love has turned into disgust. The chorus emphasizes the need to let go and move on from this toxic relationship. The repetition of "Let it swing" suggests allowing the situation to play out naturally, without putting any more effort into it. The willingness to let go is a step towards accepting that the relationship has run its course. Overall, "Pendulum" explores the complexities of love and the need for self-preservation when faced with an unhealthy and unfulfilling relationship. It encourages the listener to recognize the signs of a harmful connection and take the necessary steps to find happiness and peace.
