It was difficult for me to imagine that a shift of 8 hertz in the tuning would make any significant difference, until I tried it. Once retuned the Celestial Harp came alive in a manner it had not before. A new frequency was resonating profoundly. The vibrations of the new scale could be felt immediately. A missing presence returned. A simple adjustment of the scale A=440 to A=432 created a new sensation, a very new feel. It would be worthwhile for the curious to google A=432 as there are numerous videos on the subject. My advice is to watch more than one of them.
