The thread about Strange Singing Techniques made me start thinking. What are the techniques, characteristics, etc. that distinguish a great traditional singer. I try to listen and learn from many, but for example, when they judge traditional singing competions, what are the judges looking for? I know it's usually a percentage of song selection, voice quality, feeling, etc. But I've heard differing opinions on vibrato vs no vibrato, emotion vs no emotion, etc. Also song selection, would they be looking for a song that was unusual and rare, or one that was hard to sing (so it would show off the voice/technique)?? What about ornamentation? I'm thinking here not so much of gaelic singing, which I think has it's own rules and guidelines, more about traditional English/American/Scots ballad singing.

I realize there are lot's of differing opinions so let's try to keep things civil and polite! Oh and let's not get into what is a traditional vs. revival singer please. I'm meaning people who sing in traditional style - not one of those rare source singers that are unfortunately dying out.
