Please create a smooth, meditative background sound that embodies tranquility and healing. I'm looking for soft, calming tones that incorporate healing frequencies known for their therapeutic qualities. The composition should be gentle and flowing, reminiscent of a serene natural environment. I prefer a blend of ambient soundscapes with subtle instrumental harmonies, possibly including sounds like a gentle stream, soft wind, or distant birdsong. The overall effect should be one of peacefulness and restoration, suitable for meditation, relaxation, or as a calming backdrop for focused activities. The tempo should be slow and the dynamics should remain soft and consistent throughout the piece, providing a sense of continuous, soothing comfort.
