At twilight, a gentle deep wind sweeps through the silent pine forest, its low hum anchored by the soft tone of Wind Tone. Above, bamboo‑grove wind birds drift on the breeze, their melodic chirps weaving with the distant call of birds to paint a natural chorus. Meanwhile, the subtle flow of Deep flowing water adds a tranquil undercurrent, as rustling grasses and gentle breezes complete a balanced, contemplative soundscape.
