Mine was “faint and sad sounding” for ages and ages … it’s now at the stage where people can (with a lot of patience, and a lack of anything better to do) identify songs I’m whistling … sometimes. Keep trying, and it’ll happen!

Though it occasionally drives my co-workers up the wall, it brings me great pleasure. Keep working at it. One day you’ll surprise yourself to learn that you are, in fact, whistling!
