Something I’d like to add to the suggestions is do not forget about “Articulations.”
Jon Gindick says that bending doesn’t come from the lips and/or front of mouth – Rather, from the back of the throat.
Without the harp, with mouth open as if it had the harp in it – On on inhale, say the word “Kee” “Kee” several times. When done correctly, the back of tongue will actually drop, the ‘glottis’ area will open, and you’ll feel the rush of cool air as it rushes in.
The next part of this, on the same inhale is to say “Koo” “Koo” several times. If done correctly, the mouth, tongue and throat will take a proper wider position.
Put both Kee-Koo together; and on inhales, your mouth, throat and tongue should form to the proper embouchure for bending.
Place the harp in your mouth; on the 1, 2, 3, and/or 4 hole – “Kee-Koo” will help sound the bends you want to hear.
To remember Kee-Koo, it’s simply articulating Cookie backwards.
The interesting thing about using Kee-Koo is that it works on both lip and tongue blocks.
Over time, as you develop muscle memory, you should be able to use the “Koo” to hit the correct bend first without the need for slurring via the “Kee” portion of it.
Of course, it’s all up to you to develop these techniques; as well as only experience and your own playing will guide you when to interchangeably use either the lip or tongue blocks methods.
Hope this helps!

Rock on, yo!
