The Geminiani Project
The Geminiani string Chamber Orchestra (London) is the first modern chamber orchestra tuned at 432Hz.
The Universe was created with sound. Sound is a very powerful thing, such as the words you use or the tone you use. It has an effect. So does the tuning we are using musically. Our standardized tuning has been set to A-440hz. This was helped to be established by one of the main Nazi propagandists because they had determined that it makes people more aggressive.
Before that “standard” was established, musicians tuned to a whole range of more natural tunings such as 432hz. You can feel the difference!
