So, there are ears and there are other ears.
I don't mind at all since I don't have perfect pitch.


Me neither, WW - but I reckon we all respond to the most subtle differences nonetheless. I think it was eta (earlier in this thread) who talked about how our entire bodies resonate to music. We aren't limited to what our ears and brains can detect.

I think artful imperfection (knowing when not to follow rules) is the essence of music. "Perfect"/law abiding intervals and harmonies fail to move us in the same way as more natural/imperfect sounds. You have to be inventive to make digital sounds work on their own.

On that front, can anyone tell me why CD reproductions of analog recordings invariably sound flat and lifeless until they're remastered by someone who knows their stuff? And what does that remastering involve?
