What is 432Hz?

A different way to experience music

🎼

A Brief History

Today, virtually all music is tuned to A=440Hz — a standard set by the International Organization for Standardization in 1955. But before that, there was no universal agreement. Many orchestras tuned lower, and the legendary composer Giuseppe Verdi himself advocated for A=432Hz, sometimes called "Verdi tuning."

Why Listeners Prefer It

Many people describe 432Hz music as warmer, more relaxing, and easier to listen to for extended periods. The pitch is slightly lower than standard tuning, and listeners across millions of YouTube videos and streaming sessions have gravitated toward it as an alternative way to experience their favorite music.

🔬

What Research Says

Peer-reviewed studies have explored the effects of 432Hz tuning. A 2019 double-blind study in Explore journal found 432Hz music was associated with decreased heart rate. A 2022 study on emergency nurses found improvements in blood pressure and respiratory rate with 432Hz. Research is ongoing, and we encourage you to listen and decide for yourself.
