432 Hz is often called the “natural tuning,” believed to resonate more harmoniously with nature, the universe, and the human body. It can evoke a calming and soothing tone and is said to foster creativity, intuition, and inner tranquility.
In contrast, 440 Hz is the modern standard tuning adopted globally in the 20th century. Some listeners perceive it as more vibrant or tense—less aligned with the body’s natural rhythms—making a deeply resonant and soulful sound harder to achieve.
