What Is a Whistling?

Women whistling is not just for sorrow. Therear also accounts of women a whistlin out of happiness or joy. Even the yellow emperor is said to whistle, but the terminology here might actually mean hiss or it might mean a sigh. And in the classic of mountains and seas, the queen mother uses a whistle as a kind of battle cry to disply her ferocity. This would be a fantastic basis for a german metal band, all female metal band, that just employs whistling instead of singing.
