Conclusion

You can sing a single line many different ways, as John Jacob Niles notes:

A girl had stepped out to the edge of the little platform attached to the automobile. She began to sing. Her clothes were unbelievable dirty and ragged, and she, too, was unwashed. Her ash-blond hair hung down in long skeins …. But, best of all, she was beautiful, and in her untutored way, she could sing. She smiled as she sang, smiled rather sadly, and sang only a single line of a song. ¹

You can sing it in ways that brings people comfort, makes them sad, or which helps them to think of the divine. You can help people to make general sense of things despite the first impression that you are small, unwashed, ragged and untutored.
