Yes, 4 different ways. I've almost never been able to do it the conventional way. I have no idea why. I can get a few notes that way from time to time but can't get more than a few seconds worth. However, I CAN do it that way by inhaling! I've always been able to whistle through my teeth, just like dad but, it CAN be a strain on my jaw after a while so, I don't do it all that often, anymore. But, I CAN whistle that way by inhaling without any jaw stress. It's a bit more airy and almost sounds like a mellotron. If I'm trying to whistle a long note, I can easily switch from exhaling to inhaling without much of any change being noticed and then, when I need to exhale, just switch right back. At the moment, my nose is doing most of the whistling, for some reason!
I haven't whistled for a long time, but I wanted something. I put two fingers between my tongue and whistle and make a loud sound when I do this, I wanted to do it so bad but I couldn't succeed.
