Waves can be a metaphorical reference to the sound or movement patterns that maracas create when played. Maracas are percussion instruments that produce a shaking or rattling sound when shaken, resembling the sound of waves crashing on the shore. Additionally, the motion of shaking maracas can mimic the swaying movement of waves, creating a rhythmic and fluid sound. Overall, waves can represent the dynamic and flowing nature of music produced by maracas.
