i "play" another instrument which is whistling. not with a whistle with just my mouth. i can whistle a max. of 4 octaves of my "Low B" (right below middle C) and 2 octaves above 3rd line B. i guess that's what whistiling for hours everyday will do. plus its something like a harmonica where you can just walk around and play it whenever. someday i will get recordings and put it on my site so you can all hear me if you don't believe me
