432Hz Drone - 3 Octaves

This is a 432 Hertz Drone with 2 of its octaves. It can be used for tuning or chanting. "The current reference frequency for tuning musical instruments is 440 Hz. Musicians who use 432 Hz declare that when musical instruments are tuned to 432 Hz, music becomes “warmer” and the perceived volume seems higher at the parity of Decibel (dB). (...) Maria Renold explains in her book describing some experiments, that when listening to a piano concert with a standard pitch based on a 440 Hz LA, the listeners present in the room during the performance assumed polemic, aggressive behaviors. When the tone of the same instrument was brought to 432 Hz, the same people, once again invited to listen to the same concert, perceived the music as being better, and showed much more attention in listening. (...) NASA also shows us in real time that the terrestrial frequency is about 8 Hz (“Schumann resonance”). This would therefore be in mathematical relation with 432 Hz. " (Calamassi & Pomponi, 2019)
