I recorded a retired touring guitarist's daughter in my home studio. She sang a C note when it should have been a D. I simply moved the note up to a D; note I don't recall what pitch shifting program I was using at that time. He said that doesn't sound like her. He could tell that the harmonics/overtones for a D note are not the same for a C note. He was the only one I have ever met that could tell the difference.
