I've never managed to whistle in my life ):
... I actually pretty regularly whistle for, like. 15-20 minute stretches. More or less no breaks. Keeping the whistle going and on point on the inhale is somewhat more difficult, but possible, and once you get the trick of it it's how you keep time with not just entire songs, but entire sequences of them, including fairly complicated instrumentals. Fun stuff!
I can "cheat" somewhat while whistling in that I can whistle while inhaling air, as well as exhaling. So it's mostly about how long I can keep it up until I get tired.
I do this. It's fun heh. Trying to figure out how to do it while tongue whistling.
I was making crappy bird-like whistles which is why my wife asked me how to do it and I was stumped.
See, I kinda bite the sides of my tongue with my molars (I had all my pre-molars removed for braces so I've got spaces to slip my tongue into) and turn the tip back on itself behind me teeth, after which gentle blowing produces whistles.
Bah, why remove teeth. I still got all my wisdom teeth (they came out perfectly, but earlier this month one decided to tilt outwards a bit, ruining my bragging), even if my tongue is a mess of scar tissue.
Pfft, I have three wisdom teeth. The lower left one has kinda knackered my gum a bit ( in that it doesn't quite go to the tooth so there's a noticeable gap) but for some reason, the last wisdom tooth either doesn't exist or isn't coming in. Oh well.
