Right, I do see your point. Our daughter who was doing a degree in music said to my wife: Mum, don't sing, you've got degree qualified listening.

So let's just say 'folk orientated' singing. She has no confidence (there's a surprise) and is certainly not looking at choral.

Sorry to be a bit vague, but even she's not sure.

'Untrained sound' - describes my singing perfectly!
