Murmullo means "murmur" or "whisper". It’s a beautifully onomatopoeic word that describes a low, indistinct sound, making it very memorable.
In this song, the singer describes a mysterious call to adventure as "Es un murmullo que me avisa" (It's a murmur that lets me know). This poetic line personifies her inner voice or destiny as a subtle whisper, creating a sense of wonder and encouraging her to follow an unknown path.
What lies around the bend? In “¿Qué Será? Quiero Saber,” Mexican singer Susana Zabaleta turns uncertainty into an exciting adventure. Using the river as her favorite metaphor, she reminds us that real life is always moving: water curves, splashes, and never repeats the same shape twice. The narrator feels an irresistible murmur calling her downstream, tempting her to swap the safety of a “firm home” for the sparkling unknown.
The song is a celebration of change and a declaration of curiosity. Every “¿Qué será?” pulses with hope, encouraging us to trust our dreams, follow the current of our own desires, and treat anticipation as a source of energy instead of fear. Let the questions flow—your future might be just around the next river bend!
