I got a cheap c tuned harmonica and a book as a gift, and had fun trying to make it work. I can play some basic stuff, and could do dylan-esque blasts on it. The easiest way to get a bluesy sound out of it is to work on your wah - makes pretty much anything sound like the blues....

The note bending defeats me too.... the book describes it as moving your tongue to the roof of your mouth to bend the note... When I try it I end up with a crap whistling sound.... :rolleyes: I found this link - not sure if it'll help you.

I like messing with it though, and they cost almost nothing, so almost nothing to lose...
