Before 1955, pitch varied widely across orchestras and concert halls. Composer Giuseppe Verdi pushed for A=432Hz, calling it more natural. Today, millions of listeners seek out 432Hz versions of their favorite music. Some peer-reviewed studies have found it associated with lower heart rate and blood pressure. Whether it's science or just how it sounds to you, the difference is real.
