music is what states the mind
handle with care...
changes peoples personality if not
Research shows that music in 432 Hz, in according to the majority of the music lovers, is nicer for hearing, softer, brighter and more beautiful than music in 440 Hz. But you must have a good ear for music to hear this difference. Practically the difference is more clear with quiet and classical music than with hard, loud music.
432 Hz gives a greater clarity than 440 Hz, there's less need to play music in 432 Hz as loud as in 440 Hz.
432 Hz is more favorable for the chakras too. 440 Hz is working at the third eye chakra, "the thinking", while 432 Hz is working at the heart chakra, "the feeling". Listening to music in 432 Hz therefore accelerates the spiritual development of the music lover, although the tempo is different for everyone.
