Bajo el Azul Profundo

(Slow marimba melody begins, accompanied by soft bubble-like sounds. Deep bass swells in the background, creating a sense of depth and mystery. Gentle pads drift in like underwater currents.)

(No vocals, marimba carries the theme. The soft bubbles continue to pop rhythmically, as the pads swell and fade. Deep bass resonates, evoking the vastness of the underwater world.)

(The marimba melody expands, echoing like distant calls in the deep sea. Pads grow fuller, weaving textures of wonder and stillness. The bubble sounds become more pronounced, resembling the rising breath of a diver.)

(A subtle shift in the marimba's tone, exploring a darker, mysterious motif. The deep bass becomes more prominent, creating tension, while the pads shimmer like bioluminescent creatures in the dark.)

(The marimba returns to its original melody, now layered with subtle variations. The pads and bubbles harmonize, creating a sense of unity and flow. The deep bass remains steady, grounding the piece.)

(The marimba gradually fades, leaving the deep bass and pads to linger. The bubbles grow softer, as if disappearing into the ocean's depths. A final low swell of the bass closes the piece, leaving a sense of mystery and calm.)
