JohnCW Yeah, he probably discovered this all on his own organically, so it feels like a revelation. 😃
So here he plays a 1st and 5th while singing a perfect 3rd, once he plays the 3rd on the piano, it sounds pretty bad with his voice. As a singer with an excellent sense of pitch, I imagine this can be infuriating!
Usually it's the other way around, the instrumentalists complaining about singers never being on pitch. 🙂
pianoloverus I saw him several decades ago play his special piano at Faust Harrison Pianos in New York City. If I remember correctly, and I'm not sure about this, he had the special rods he could insert into a piano tuned the normal way that allowed the piano to produce the theoretically correct notes in different keys.
That's very informative and fascinating, thank you! I'll look this up!
