The Importance of Distance in Whistling

The distance thing is a very important component, either distance or an environment where sound is absorbed like a forest. There's actually one more parallel between writing and whistling that is relevant specifically to the strain on your vocal tract from trying to communicate motally normally over very long distances. Whistle registers usually will permit people to whistle just without any tools like you can whistle without any tools. But the precise means in which the whistle is produced does not matter.
