Trills
There are two basic trills used by blues harp players, the hole 4 and 5 draw trill and the hole 3 and 4 draw trill. The idea here is pretty simple. You just draw in on the harp and move the harp back and forth across your mouth either with your hands or by shaking your head. Mastering these trills is not easy however. Again, you have to be careful to sound each note individually or the effect will not be the desired one. Once you have mastered the basic trills you can try things like bending the trilled notes while you trill. You can also experiment with finding other trills on the harp on your own.
The trills look like this:
