Music with sound harmony tuned at the frequency A4=432Hz.
When compared to music tuned at the ISO standard A4=440Hz, experts say that "the sound harmony of music tuned at A4=432Hz feels more cored in the low-frequency end, warmer in the mid-range, and more transparent and spacious in the high-frequency range". 432Hz music really sounds better.
This natural tuning was used, in the past, by many famous classic composers.
In the early 1950's a (small) Committee was selected to decide upon an "International Tuning Standard". They chose (badly) A4=440Hz, instead of 432Hz. Why? Do your research.
