432Hz is a frequency that is said to be harmonically consistent with the natural vibrational frequencies of the universe. This means that when music is tuned to 432Hz, it is thought to be more in line with the natural frequency of the earth and the human body, and therefore has the potential to be more soothing and healing. Some people believe that listening to music tuned to 432Hz can have positive effects on the mind and body, and can help to reduce stress and promote relaxation. However, there is no scientific evidence to support these claims, and the idea that 432Hz is the "natural" frequency of the universe is not widely accepted by the scientific community.
