It's true though, wouldn't you say? I've noticed that in a lot of other countries I've lived in people generally seem able to read music fluently and are able to sing confidently and in tune. Or if they cannot read music, they seem able and happy enough to sing something by ear. Often when you are at parties or spend an evening with people, they'll strike up songs and I don't mean drunken yowling.
I'm also not referring to specifically musically trained people but just generally it seems to be a way of life that goes through all classes/professions. I really noticed this in Denmark for instance or Russia, where everyone seems able to sing something well and do it confidently and looking as if they enjoy it.
So why is it not like that in the UK I wonder? Is it a skill that's gone lost over the years?
