Thanks to all of you for your input. It seemed as though most of the threads on music were largely about accompaniment or accompanied songs. I couldn't detect anything about people who sang unaccompanied.

My conversation with Tom Lewis occurred right after we had seen a workshop on unaccompanied voice. The workshop had included Louis Killen and four or five others including the members of one of the great British chanty groups (I think it was Hearts Of Oak).

I'm hearing a lot of you saying you sing Celtic music unaccompanied. Is there something special about the Anglo-Irish-Scots music that lends itself especially to the unaccompanied voice? Even the American songs I've heard sung unaccompanied and solo seem to relate to that cultural heritage.

Opinions?
