"By the way, David. Whether one is singing off-pitch or not is not subjective. This is scientifically measurable." (Don)...I didn't say either - I said whether folks happen to like particular piece can be subjective...one man's meat...
And Volga added on - I watch Songs of Praise (BBC) nearly every week, and have some good Christian recordings, and am sure that the top singers in this genre are affecting their voice so as to sound sweeter, more-angelic, etc.
And, from the "Chords in Folk?" thread, it was said that English folk music is not all about the tune but it is/has been mostly
so.
